What is the knowledge of the Son of God? Paul writes, "Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away. Our knowledge is in part... For we know in part, and we prophesy in part. But when that which is perfect is come. (1Cor.13:9-12)This when the Church comes to a perfect man. (Eph.4:11-16) Then that which is in part (knowledge, prophecy, tongues) shall be done away. There is a perfect to come... When I was a child, I spake as a child, I understood as a child, I thought as a child. At this present time we are a child. But when I became a man, (i.e. a perfect man Eph.4:11-16, Heb.5:11-14, 1Cor.13:9-12) I put away childish things. (knowing in part, prophecy, tongues) As of today... For now (today) we see through a glass, (The Word of God - James.1:22-25, 2Cor.3:18) darkly; (as a child, knowing in part) but then face to face: (marriage language) now I know in part; but then shall I know even as also I am known." (consummation of the marriage of Christ and His Church. Note: Gen.4:1) (1Cor.13:8-12) What is a Perfect man?
