Introduction
Why does time flow the way it does?
Can we alter time, or is it beyond our grasp? Is time travel possible? Is God
inside or outside of time? Does everyone experience time the same way we do? When
faced with the question, What is time? we encounter one of the most fundamental
human inquiries, as well as one of the most difficult philosophical questions. Every
person seems to experience the flow of time every single day, yet when asked to
define it, we are often at a loss for words. Thus, for the purpose of this
article, we shall define time as a relation of events involving “earlier than”
and “later than.”
Two views of time
When it comes to the philosophy of
the nature of time, there are essentially two views: the dynamic, tensed, or
A Theory; and the static, tenseless, or B Theory. It is
traditionally said that on the A Theory, the present is ontologically
privileged. That is to say, the present is the only thing that is really real;
the past has happened and the future will happen. It is much easier to see what
distinguishes the A Theory when it is compared with the B Theory,
which holds that all moments are equally real. That is (according to the B
Theory), from our perspective it is 2007, 1950 is in the past and 2050 is
in the future. But for the people in 1950 (who also exist at that time),
both 2007 and 2050 are in the future. Likewise, for the people in 2050 both 1950
and 2007 are in the past. The B Theory holds that it is ignorant to
think of our moment of the world as the “real” moment, or the moment occupying
some privileged position. According to the B Theory, any tensed idea, or
sentence whose verb has tense (i.e., past/present/or future), would actually be
more accurate if it were translated into a tenseless idea or sentence (i.e.,
one that has a “tenseless” verb and time stamp to say when something happened,
rather than a tensed verb) since tensed ideas imply that the present moment of
time is superior to, or more real than, all other moments. For instance, according
to the B Theory, the tensed sentence, “JFK was assassinated,” would
misconstrue reality as if the year 2007 (or any year after 1963) is more real
or significant than the years 1907 or 1963, because it has a verb in the past
tense. This theory holds that the sentence would be better put “On November 22,
1963, at 12:30 P.M. CST JFK is assassinated.”{2} This tenseless sentence
is preferred on the B Theory because there is no moment that can claim
to be the true present moment; rather, there are just equally real moments. Advocates
of the B Theory say that reality is one long 4-dimensional block, and we
are just experiencing one moment of that block, but all the moments are equally
real or existent. The A Theory, on the other hand, would say that tensed
verbs (verbs in the past/present/future tense) do reflect reality; there
really is a past, present, and future, and they are always changing as time
flows and the future becomes present and then past.
Which one of these views is correct
has vast implications for the way we interpret reality. For example, it will
have an effect on the way we understand God and His relation to the world. One
might think that this would be the proper time to turn to Scripture to see
whether it supports an A or B Theory. However, it’s important to
recognize the fact that Scripture is not entirely clear with respect to this
issue. Therefore, we will postpone looking at the Bible until our discussion of
God’s relation to time. For the present, we need to discuss which of the two
theories is superior and why.
A vs. B
The most powerful argument for the A
Theory is its intuitiveness. That is, we experience the flow of time in
just as real a way as any other experience in our lives. We very directly
experience the present. To say that event “e” is occurring now is no different
than saying that event “e” is occurring.{3} When we look forward to
the future or regret the past, we are experiencing the A Theory because,
if you think about it, on the B Theory there is no difference between
past, present, and future.{4} Lastly, when a kid says: “I wish it were Christmas
morning,” or “I wish I were already done with this test,” he is expressing the A
Theory. That is, he wishes that the present moment, say “t1,”
were replaced by some other moment, say “t2.” This expresses the
idea of temporal becoming (the idea that the present moment changes as
we pass through time), which is an experience of the A Theory. As
William Lane Craig puts it, “We thereby presuppose the reality of temporal
becoming, since our wish expresses our belief in a changing and objective
present.”{5} Thus the A Theory very comfortably coheres with what we
experience in everyday life.
Now, the B theorist may ask, Why
accept this experience as anything more than an illusion? To answer this we
must briefly digress with a discussion of Alvin Plantinga’s epistemology,
or theory of knowledge. When evaluating beliefs, many skeptics want to reject
anything that is not certain. This was especially prominent in the philosophy
of René Descartes, who rejected all his sense experience because it could have
been wrong. After all, when you think about it, we could be in the Matrix.{6}
It could be that everything you think is real is just electrical impulses
interpreted by your brain. Or it could be that the world was created five
minutes ago, and you were created with all the memories you currently have. Or
maybe you are the only mind in the universe, and everyone else is just a robot,
cleverly designed to give the appearance of having a human mind. And the list of
possibilities goes on and on. None of these can be disproven, but should we
conclude that we really don’t know whether anyone else actually exists? Plantinga
doesn’t think so. He has developed a theory that labels these and other similar
beliefs as properly basic beliefs.
Think about it this way. If you are
reading this online, the belief that there is a computer in front of you is
“properly basic”; that is, it is a foundational belief formed in correct
circumstances. Therefore, you are warranted in believing it until presented
with some defeater of your belief. In this case, a defeater would
have to be some good reason to believe that your senses are deceiving you. In
other words, according to Plantinga, common sense beliefs about sensory
experience, memory, the existence of other minds or other similar beliefs should
be regarded as innocent until proven guilty (i.e., judged reliable until proven
otherwise). Likewise, our experience of real temporal passing and an objective
past, present, and future warrants belief in the A Theory until a strong
counterargument is offered—strong enough to cause us to doubt this experience.
Another major argument for the A
Theory is what is known as the ineliminability of tense.{7} Simply put,
this is the idea that tensed statements imply tensed facts which further imply
a tensed reality. B theorists have made numerous attempts to show that tensed
sentences can be translated into tenseless sentences that do not imply a tensed
reality. However, all these attempts have failed. Craig illustrates:
This point is underlined by the
ineptness of some of the supposed tenseless translations of tensed sentences. Take,
for example, the tensed sentence “It is now 4:30.” We can imagine situations in
which a person’s life would depend on his holding such a belief. But the
tenseless counterpart of this sentence is either “It is 4:30 at 4:30,” which is
a mere tautology, or “It is 4:30 simultaneous with this utterance,” which is
useless unless we also know that “This utterance is occurring now,” which is a
tensed belief. In both cases the tenseless versions are insufficient to
motivate timely action because they do not inform us whether or not it actually
is 4:30.{8}
If tensed sentences lose some
meaning when translated into tenseless sentences, then there is some important
meaning in tense, namely, that reality is reflected by tense. Therefore, if
tenseless sentences cannot capture the facts expressed by tensed sentences,
then there must be tensed facts. And thus we have a strong argument for
temporal reality.
Next we turn our attention to some
problems with the B Theory of time. While there are numerous problems,
we will discuss just two of them.{9} First, the B Theory of time greatly
misconstrues some biblical ideas, one example being the doctrine of creation
ex nihilo. For the B theorist, the universe beginning to exist simply means
that it has a starting point, just like a yard stick has a first inch.{10} The problem is that on this view “There is in the actual world no state
of affairs of God existing alone without the space-time universe. God never
really brings the universe into being; as a whole it co-exists timelessly with
Him.”{11} So while the universe depends on God, the idea of creation ex
nihilo is severely stripped of meaning since the universe always timelessly
exists with God. That is, in some sense, God and space-time seem to be equally
necessary in their existence.
The other major biblical problem is
that evil is never really vanquished.{12} “On the static theory of time [B
Theory], evil is never really vanquished from the world: It exists just as
sturdily as ever at its various locations in space-time, even if those
locations are all earlier than some point in cosmic time (for example, Judgment
Day).”{13}
Furthermore, events like the
crucifixion are never “past” or done away with. They simply remain timelessly
forever, which seems hard to reconcile with Christ’s victory over death.
A second argument against the B
Theory has to do with the impossibility of the existence of actual
infinites. It has now been almost universally agreed upon by mathematicians
and philosophers that an actually infinite number of things cannot be
actualized in the space-time universe. The idea of actual infinites creates
many paradoxes. For instance, what is infinity minus infinity? Well
mathematically one gets contradictory answers. For example, one could say that
the answer is infinity. But the answer could also be 4, or 0, or any other
number you want. This led the great mathematician David Hilbert to say, “The
infinite is nowhere to be found in reality. It neither exists in nature, nor
provides a legitimate basis for rational thought...the role that remains for
the infinite to play is solely that of an idea.”{14}
Thus, what we have in the
space-time universe are not actual infinites, but potential infinites.
For example, you can start counting 1, 2, 3, 4, 5… and continue this process for
a potentially infinite time (i.e., you can keep going as long as you want). But
you will never reach a moment when you can stand up and exclaim, “I’m done! I’ve
counted to infinity!” In the same way a line three inches in length can be
divided in half, and then in half again, and then in half again, ad infinitum. But
it can never actually be divided an infinite number of times. For this reason, in
addition to compelling scientific and theological evidence, essentially all philosophers
and scientists have now come to believe that time is finite in the past.
However, the future is different. We
know that the future is not finite but infinite. We know this both
philosophically and biblically by the promise of everlasting or eternal
life. Therefore, most scholars have concluded that the future, like numbers, is
potentially infinite. We can keep adding years forever, but we will never reach
an end. But this is inconsistent with the B Theory. Since every moment
of time in fact exists at once, and the future has no end, there is an actually
infinite number of years in the future. But since we know that there are no
actualized infinites in the real world, we can safely conclude that the B
Theory is wrong in its description of the future.
So we have seen two strong
arguments for the A Theory, from our experience of temporal reality and
the ineliminability of tense in language, and two ways that the B Theory
seems clearly implausible, from creation ex nihilo and the impossibility
of actual infinites. Other attempts have been made to revive the B
Theory, but suffice it to say that they have been answered thoroughly.{15}
God’s Relation to Time
We now turn to how an infinite God
relates to our passage of time. There are some things of which we are certain. First,
time began a finite time ago. We know this from the Bible,{16} philosophy,{17}
and science.{18} Second, we know God neither began to exist, nor will He ever
cease to exist.{19} We can further conclude that God existed before time.{20} This
is best exemplified in Jude 25: “...To the only God our Savior, through Jesus
Christ our Lord, be glory, majesty, dominion and authority, before all time
and now and forever. Amen.”{21} Since we know that God existed “before time,”{22} we can conclude that without the universe, God existed timelessly.{23}
We then must ask ourselves, how
does God relate to the universe since it began? Here again we find two common
positions. One is that God is “timeless.” By this it is meant that God, while
the creator and sustainer of the world, was not affected by the creation of the
world and remains constant outside the universe, just as He was before the act
of creation. The other common position is that God is temporal. That
does not mean that God is limited by time, but rather that He is intimately
related to temporal things. He thus has a past, present, and future, just like
other temporal things. Since there is no beginning or end to His existence,
this position is also sometimes called omnitemporality.
There are two main arguments in
favor of God’s omnitemporality. First, there is the argument from God’s
relation to the universe. When God brought the universe into being, He stood in
new relationships that He did not have before. Once the universe exists, He now
“is the sustainer of” and “is co-existent with” the universe.{24} He could have
remained timeless, but since He created the universe He went through an extrinsic
change.{25} If God undergoes this change, then surely He must be
temporal. That is, we can speak of a past, present and future for God. In the
past He had one relation and in the present He has another relation. This
provides a way to associate God with time, and that is all the omnitemporal view
of God requires.
The second major argument for God’s
omnitemporality comes from His omniscience—specifically, His knowledge
of tensed facts.{26} That is, as the present is constantly changing, true
sentences are constantly changing. For instance, there are tenseless truths
that are always true such as: “The World Trade Centers are attacked on
September 11, 2001.” However, on September 10, 2001, the sentence “The World
Trade Centers will be attacked tomorrow” was true, but this statement is not
true on September 11th. What is true on September 11th is
the statement, “The World Trade Centers are being attacked today.” Finally, any
time since then, the true statement has been, “The World Trade Centers were
attacked on September 11th.” All of these statements can be true or
false depending on when they are made. That is because the verbs relate the
sentence to the present. Thus, a God who knows only tenseless truths (as the tenseless
view of God proposes) would seem to be very ignorant indeed, for there are
seemingly limitless things He would not know. However, if God does possess
knowledge of the truth of tensed sentences, this would seem to make Him
temporal. As Dr. Craig puts it, “any being which does know tensed facts cannot
be timeless, for his knowledge must be in constant flux, as the tensed facts
known by him change.”{27} Thus we have a second powerful argument for God being
temporal .
On the other hand, the major
argument for God’s timelessness is what is known as the incompleteness of
temporal life.{28} This is the idea that temporal life is so limited that a
perfect God would not experience it. Certainly the fleetingness of our own
lives has led to many existential questions of the meaning of life given that
it will all end relatively shortly. Surely God would not be limited in this way.
Well, this is a plausible argument and does carry some weight, but I am not
sure how much. For one thing, because of God’s complete omniscience and ability
to experience whatever He wants, the past is never really “lost” to God, which
makes temporality far less of a limitation. Secondly, since He never ends, and
we His children never cease to be in company with Him (assuming we have
received His free gift of eternal life), there really is no need for Him to try
to grasp onto fleeting moments as we so often do. So, while this argument seems
plausible, it does not seem to me to be remotely powerful enough to call into
question the powerful arguments we have for the omnitemporality of God.
Thus, it seems we have good reason
to think that “God is timeless without creation and temporal since creation.”{29}
But it is important to remember that He did not have to create. Rather, “His free
decision to create a temporal world also constitutes a free decision on His
part to exist temporally.”{30} Many would now ask how it makes sense for God to
exist timelessly and then temporally. It seems plausible to say that time is a
relation of events. That is, God’s existence without creation was just simple,
unchanging Trinitarian perfection, and it does not make sense to talk about
“before” and “after” when there was no change. However, at the moment of the
creation, we now have an event, and we can start relating events by temporal
distance from the creation. Thus we conclude that God existed timelessly, and
then created time and space, giving us the first mark of time, and time has
been flowing ever since.
So then, we have seen that there is
a real past, present, and future. God, though timeless, created, thus giving us
temporal relations. We can speak of past, present, and future for God since He
is intimately related to temporal things and has temporal knowledge. Since the
first event, we now have a flow of time that will never end as we live on into
eternity with or without God.

You never changed, but you went through extrinsic relational changes in that you were related to me by the “in front of” relation and now you are related to me by the “behind” relation.
