God is absolute rather than relative. It is us who are relative to Him. He is the Subject, and we the object. God relates to man according to man’s relation to God. God’s action may be different in relation to one man versus another man, for it is men that vary and God that is stationary. God is constant, but we are not. Thus God responds consistently as Himself, but we being relative to Him are responded to according to our positional relation to Him.
Men change, God does not. Therefore if God still responded to man like man was yesterday, then God would be operating according to the past rather than the present. However, God is always the eternal now, having no past and no future. He doesn’t exist in time, but is the Creator of time. His existence is outside of time, distinct from time, separate and above that which is created. He only enters into time by choice, but does not have His habitation within time. This is why man being united with God has a new eternal home for our nature rises to have relationship with Him because He has already descended so that we may ascend. God doesn’t come and join us in time, but has us join Him in eternity releasing us from the bounds of time. This is why Jesus went to prepare a place for us in heaven for us to have our being in His Being in His home which is now also ours.
We were born eternal and were subjected to temporal existence when we fell from our relation to God. Peter Kreeft writes, “Being became a being, the Subject became an object, God became a man, I AM became He” expressly to release us from our fallen existence to a place of being sons and daughters of God.
Kreeft writes, “Jesus was not God represented, but God presented, God made maximally present, God known by sight and even touch as well as by faith. Heaven had come to earth. It was not a new concept of heaven but a new presence of Heaven.” Moreover he explains, “In all His encounters, He becomes in time what He is eternally.”
God does not manifest in time differently than He really is. He is always Himself weather as the Father or as the Son. He enters time to reveal Himself to us, for we could not know Him unless He manifested His identity in a way we can know. He has done this in creation, in the Incarnation, in the revelation of Scripture, and He does this forevermore through Christ.
Christ, now having habitation in us since we are lifted up to also be in Him, reflects through us to the world. We become the agents of His body manifesting His heavenly reality, where we have our being, to this earth where we live as foreigners. The cross is both horizontal and vertical. It bridges heaven and earth, but also distributes heaven to earth making the latter reflect the true glory of the former.
