How do you define God? Literally speaking, how does a finite mind somehow come to the conclusion that an infinite being can be defined and clearly laid out in a systematic format? This is not meant to exhaust God, because I will never be capable of doing that. I just want to remind us all who it is that we worship!
God by nature is eternal. What does this mean? His eternality conveys the groundbreaking truth that He exists at all points of time and eternity simultaneously. He lives now…just as He exists now…just as He inhabits now…! There is not and has never been nor will there ever be a moment in which He is not. 400,000,000,000,000 (trillion) years ago, if you could say such a thing, God is living and dwelling there right now as you read this. Vice versa, God also fully inhabits 400,000,000,000,000 (trillion) years from now and He is in perfect harmony. 4000 B.C. is no different for Him than 2013 A.D. because He exists at all points of time and eternity concurrently.
God by nature is omnipresent. This theological term means that God is present in all places at all times. So as we speak, God is in Missouri, Wisconsin, Brazil, Russia, Egypt, and Australia all at once. He stretches to the farthest reaches of outer space all the way to the highest of mountains on planet earth, and on into heaven and hell (Psalm 139:7-8), and at no point in time is He ever not residing everywhere. Thus, if God is everywhere at the same time and simultaneously being eternal at all points of eternity (past, present, and future) and being everywhere there is to be within each of those points, then just take some time and meditate upon what that means according to showing forth His power.
Finally, God by nature is omniscient, which means that He holds and possesses all that there is to know. He knows absolutely everything to the highest degree and form of being known and beyond. He does not, however, just know everything; He knows more than everything. He has more knowledge than any of us will ever be capable of tapping into. Being everywhere present at and in all points of time and eternity and possessing all knowledge about all things and more, He is supreme and we are to give glory to whom glory rightly belongs, and that is Christ Jesus our Lord.
The picture below is an illustration for this concept. The dot represents a human life. It could be yours or mine, but for this visual representation imagine it's you. The short segment above it depicts time and shows the beginning and the end of time as we know it to be. Above that is drawn a line, but the arrows are dotted, and I did this for a reason. Last but not least, on top is a full double arrow pointing in both directions describing God.
Now you may be wondering what this means, so let me explain. Imagine the dotted arrow pointing right on the eternity scale represents all of eternity future (the rest of forever). 400,000,000,000,000 (trillion) years from now God knows exactly where you will be, why you will be there, what you will be thinking/doing, when you will take each step in movement and who you will be with. He knows this because He is already there with you. Eternity does not end, but if somehow you could come to its edge and stand at the end, God is higher and further than that.
Same principle goes for eternity past (forever ago). 400,000,000,000,000 (trillion) years ago God knows where He was, why He was there, what He was thinking/doing, when He would make every move and that He was only with Himself in His tri-unified nature because in an eternal sense, there is no past tense. He is there right now and if for some miracle you could find yourself at the beginning of eternity, which there is no such thing, but if you could, then you would see that God is higher and further and before even that.
What I am trying to reveal to you is that God in the very fullness of His nature is not eternal the way many of us think. He is not bound by time nor is He held by eternity. He is holding eternity in the palm of His hand. This is how big our God is and He is larger than we can ever imagine! He holds all of eternity in His grasp and He is in sovereign control of everything that happens.
Think of all of the prophecies in the Old Testament. Within the eternality of God, technically He was never telling the future. He was, but really He was giving you and I and all of the people of Israel a history lesson. To Him, all of these prophecies have already taken place. There is a sense in which they haven't, yet there is another sense in which they have.
This attribute of God's eternality is where the cult of Mormonism really falls apart. They say that God was created by another god who was created by another god and so on down the line for all of eternity; but if you think about it logically you find that scenario to be an impossibility.
For example: Try counting backwards to infinity. Start with zero and just continue counting in the negative until you reach infinity (0, -1, -2, -3...), then once you are there, try counting back to zero. This sequence is not improbable; it is impossible! Think about it. You will never even reach negative infinity because it never ends, therefore you will never find yourself counting back to zero. If zero represents us, then according to that god after god after god thinking, we would never in all of eternity ever exist. This destroys their argument.
For us to be here right now, we must have been created by the God who is not part of eternity, but who is Himself above eternity. He must exist at all points infinitely past and infinitely present and infinitely future all at once in order to have so well designed us and the universe as majestic as He did.
"Now to Him who is able to do far more abundantly beyond all that we ask or think, according to the power that works within us..." -Ephesians 3:20
Probably the number one thing I love about the verse above is that even in eternity, it will still apply. I read this and my mouth drops in awe because I know I can think of a lot. I have a crazy imagination, but what a joy it is to my heart to know that He is far above that! I hope this is an encouragement to know that God is big and He has big plans for all of His children! Think about it! Our God is higher than eternity and He is the meaning of infinite!
