The exciting point for us is that when we are members of Christ's body, this is bringing us into membership with God. Will the time ever come in the hereafter when we can be called God, individually, like the Father or the Son might be? I think that our understanding of this idea is incomplete enough in this life to be able to answer properly.
I believe that 'God' is more like a rank/title. The highest rank/title any living being could possibly obtain in creation.
I also think that a time will indeed come in the hereafter when we can be called (obtain the title of) God, individually, like the Father or the Son, just as you have mentioned.
Psalm 82:6"I have said, Ye are gods; and all of you are children of the most High."
Isaiah 41:23"Shew the things that are to come hereafter, that we may know that ye are gods: yea, do good, or do evil, that we may be dismayed, and behold it together."
John 10:34-35"
34 Jesus answered them, Is it not written in your law, I said, Ye are gods?
35 If he called them gods, unto whom the word of God came, and the scripture cannot be broken;"
For in the end we will all be in agreement in regards to all things, both in heart and in mind.
Although as you say, it is unlikely that we will be able to understand it in its entirety during this temporary life of ours.
Yet all will be revealed in its proper time. And it shall be exciting indeed
One thing that makes this so difficult to understand, has to do with the almightiness of God.
God is all powerful; He can make or do anything.
God knows everything; nothing can set itself up against His knowledge.
God is everywhere at all times, superseding space and time.
In other words, God is almighty... maybe. "Maybe" because, is God almighty in lack of almightiness?
That is one of the major parts of God's almightiness... that He can be almighty in
non-almightiness.That is what God is in people. People are weak - God didn't want them to become so weak that they would fall into sin and die. Yet, as Elihu says in Job, "If it were his intention and he withdrew his spirit and breath, all humanity would perish together and mankind would return to the dust."
The word "breath" is also the Ancient Hebrew, the word for "spirit" and "wind." It signifies that freeish-from-God mankind (wind) was a spirit (like God) but also weak (beath). It's somewhat like God is saying spirit and spirit, the spirit of man being weak, but being constantly visited upon by the Spirit of God Who is strong.
In the fact of being like God and unlike God, mankind is the way God would be if God were not almighty. The fact that God's Spirit is with man's spirit (the double spirit in Job), is that God is experiencing and living the weakness right along with man. So, God is almighty in weakness, so that He can really be almighty in every way.
Will we ever become strong in Eternity, like God? Or will God always keep us weak, yet be right with us, so that He will always be shown to be strong in weakness. Where else in the Bible do have we this?
Saint Paul says in 2 Corinthians, "Therefore, in order to keep me from becoming conceited, I was given a thorn in my flesh, a messenger of Satan, to torment me. Three times I pleaded with the Lord to take it away from me. But he said to me,
'My grace is sufficient for you, for my power is made perfect in weakness.' Therefore I will boast all the more gladly about my weaknesses, so that Christ’s power may rest on me. That is why, for Christ’s sake, I delight in weaknesses, in insults, in hardships, in persecutions, in difficulties. For when I am weak, then I am strong."
Notice that God's strength is made perfect in weakness. I suggest that Jesus answered Paul by stating the same thing that I have been showing above... that our God-likeness in weakness, with God present with us at all times, is the way that God is making Himself have "weakness almightiness," so that God is almighty in all things, even in weakness.
Along with Paul I say that I don't want to be too strong in myself, but I want to be held up by God's strength, so that God's strength is made more perfect in my weakness.
Will this weakness be for the whole of eternity and beyond?... except that it will be in perfection in Heaven, of course. I don't know. But God does. And when we get to Heaven, we just might understand way more clearly. But even then, there might be some aspect of weakness that remains in us. Why? Because who can predict what the free will of God or a God-like person will dictate? Even Jesus was astonished at the faith of the centurion.
