[This is a first draft from a small section of my upcoming Systematic Theology book]
“Praise the Lord, the God of Israel,
who lives from everlasting to everlasting,”
Psalm 41:13 NLT
“there he worshiped the Lord, the Eternal God
Genesis 21:33 NLT
God is timeless, or exists in an “eternal state.” What does that mean?
God is Spirit, Power and intellectual. Thus, what is timeless is spiritual, intellectual force.
Time is a measure of change. Without any change, in any degree, there is nothing to measure, and if there is nothing to measure, then the concept of time is meaningless and nonsense.
Thus, all material existence is automatically ruled out in being attributed with timelessness, because all material things change. Even invisible things like the mind of man, changes as man learns new things; however, we will focus on the issue that matter is not timeless.
Vincent Cheung commenting on this says,
Matter cannot be eternal, in the sense of being timeless, for there is no before and after with that which is timeless. And if there is no before and after with matter, then it would be impossible for it to be one way before and another way after. Therefore, if matter changes at all, it cannot be eternal. And matter could not have existed forever, for if matter is bound to time but has existed forever, then it would have an infinite past. But if it has an infinite past, it could never have reached the present. If it has reached the present, the past cannot be infinite. Therefore, matter is not eternal, but bound to time, and it originated at some point in time.
God is uncreated. He is eternal, timeless, and immutable. And he created the universe out of nothing, that is, without the use of any existing materials, since there were no existing materials when he created. All linguistic and historical arguments that attempt to suggest an opposing view must be wrong. In fact, these kinds of arguments are irrelevant unless the logical arguments based on the very ideas of matter and creation are demonstrated to be inconclusive.
To further explain this. By this we know that any naturalistic or evolutionary claim that matter has “always existed” is bottom of the barrel stupid. To always exist with change, would mean an “infinite” chronological measurable time/distance. Another way to say infinite in regard to time or distance, would be “an unreachable distance.” If it is reachable, then it is not infinite; matter’s history of change is not an unreachable distance, if the distance to the past is reachable. Evolution teaches matter has always been here; they say this because if it was not, then either matter was created, or “self-created,” which is a contradiction. Either is not acceptable for evolution. Thus, since timeless is out of the question, they make matter eternal. However, that is a contradiction, and as shown before, a contradiction does not exist in the mind or in reality. To say matter has an “unreachable” distance going into the past, yet, we have “reached” this “unreachable” distance by being here today, is Plus Ultra Stupid.
God, as the Scripture says, exists from “everlasting to everlasting,” and this is as the “I AM who I AM.” He is also said to be immutable. And so, the I AM who I AM, has always been that way, and will forever be that way. Thus, God’s existence is not eternal properties that might change; rather, God’s existence is an eternal state. For this reason, “emotions,” are not part of the Divine Nature. Emotions change, but God does not change. God is timeless; yet, emotions by definition are measurable, and thus, are not timeless.
Therefore, what is timeless is God’s mind, or what is timeless is God’s powerful thoughts about all things. There is nothing to measure in God’s eternal state, because there is no change. Thus, God’s thoughts are not learned. God’s thoughts are not in a linear progression like man is with his limitations. God has always self-existed as intuitively knowing all things in “one thought” (i.e. “eternal unchanging state”), without progression. God did not have to wait to create, to see (although this is wrong because God does not have eyes) images to associate certain thoughts with things to know them better. God has always known that He would create. Included in God’s thoughts about all things, as an intuitive and never changing thought, was creation. This is why after creation, God does not change. This is why God is not different between the Old Testament or the New Testament. The eternal state of God’s intuitive thought about all things, has not changed.
God is also said to be perfect. And thus, for God to change is not only a denial of His timelessness, but it would be a change for the worse; it would be to liberate from perfection; it would make Him less valuable; it would be a serious downgrade. If you have been following what has been said about God’s nature, for God to change it would mean God would have to exchange a truth for a lie. This is an impossibility.
This does not mean there is no such thing as logic or order to God’s mind; rather, it means the logical order of God’s mind was not chronological in time, but always known intuitively as one thought. For example, the decrees of God. God ordered the history of the world, before it was created. But this ordering has always self-existed with God as one intuitive thought. For man, who is not timeless and has a limited about of thoughts they can think in any given moment needs time and a progression of thoughts to see this ordering. This will be discussed more later, but the same is for logic and God. Because God has already known all things, it means any thought applied to creation is a deduction for God, because it is merely pinpointing specific information that was part of God’s original timeless intuitive thought. For God, any specific thought about creation, does not add more information to His conclusion. For my readers, this section is dealing with many abstract concepts, however, to help see this, consider it with Jesus. Starting with Jesus’ divine mind before creation and His timeless eternal intuitive thought about all things, then go down to the incarnated Jesus who limited His mind (but the Divine Mind did not stop or change), any thought He had is still just a deduction from His timeless intuitive thought about all things (Even what He would think and say as His time as incarnated Jesus).

 Vincent Cheung in an email first brought this to my attention, when I was discussing logic with him. Once I thought about it, it was rather obvious God’s thoughts are deductive by plain definition.
