On the Cross, Jesus refutes your assertion that God's life is in eberyone. When Jesus died, He died as a man without God's Life in His human spirit else He would not have been able to die, and die in our stead. God made humankind to have a spirit, but we have inherited from Adam a human spirit without God's life in it. Jesus IS the cure for that, in that He is the 'last Adam and thus the Being from whom we may inherit a new Life via our will turned to believe on Him. While Jesus walked the Earth with His disciples, he was 'in' a human body with a human behavior mechanism (a human soul), but His human soul was unique in that His human soul also had God's Spirit Life in His human spirit. It was when that Life left Him on the Cross that He cried out, 'Eloi Eloi, lama sabakthani' ... the human of Jesus, not The Word made flesh, died on that cross and was buried in a borrowed tomb. The Life of God came back to Jesus the human body as The Word made flesh became yet again a quickening Spirit.
Each of us may have that same Life imparted to our 'dead' human spirit, by believing on Him Whom God sent for our new birth into a new man. When we do what God requires, we are immediately made a new creation. As we walk thereafter, if we will allow Him to do it, we will be transformed along the alignment with this New Life in our before dead human spirit now alive in Christ, just as He told Philip that He is in God and God is in Him.
