None of your comments, though interesting, answer the actual OP questions.
"Does God have size? If God has size, how big is He? If God has size now, was God always this big?"
The question is not asked with IMO intellectual honesty. First, of HE, we know how much space God needs, and one asked, Who made the space for him? That question is asked because one doesn't:
1. know the God of the Bible
2. will not accept God as the Creator
3. God is outside of time, Space, and Matter.
The God of the Bible says I Am the Self-Existing One with No beginning and no End. One accepts that or doesn't
My proposition is that God is love, holy, merciful, just... and time and space. So no one made space for God. Prove me wrong from scripture. Where does scripture say God made tme and space, rather than God made a beginning for the world and made the world within His space?
If the God of the bible is a mystery, how do you knpw your own inferences about Him are true? And how were you authorised to arbitrate on the accuracy of other people's different inferences about God. I use the bible, the cross and logic to arrive at my inferences about God. I have shown scripture in this thread that says Cod is everywhere. I cannot escape His presence. If I ascend to heaven He is there. If I descend to sheol He is there. He is in every believer. How can these be true if His spirit is not spacial so that He is imminent within all things? You are proposing a contradiction to these biblical statements that is not stated within scripture. Why? Where does you idea come from?
How can you say I don't know the God of the Bible but you do, when my propositions are clearly stated in the Bible and yours are not?
How can you say I will not accept God as creator, when I have referred to Him creating many times in this thread?
How can you assert God is outside of time and space when scripture clearly states the opposite, and does not state what you assert?
