Enlightenment:
Eve could be the increase of Adam because she was constituted with the rib of Adam and became one flesh with Adam, a part of Adam. In the same principle, we can be the increase of Christ because we are spiritually constituted with the life of Christ and have become one spirit with Him, a part of Him. As Eve came out of Adam and returned to be one with Adam, thus becoming Adam’s increase, so we also have come out of Christ and will return to be one with Him, thus becoming His increase. This increase is just His reproduction in us through regeneration. All the people who participate in this reproduction are given to Christ by God.
Verse 30 says that Christ must increase and that we all must decrease. Why? Because Christ is unlimited and all-inclusive. These verses reveal an unlimited Christ. He was the little Jesus who was born in a manger and raised in Nazareth in the house of a poor carpenter. He had no outward beauty or attractiveness and He was very limited. Nevertheless, He is all-inclusive, immeasurable. He is higher than the heavens and broader than the universe. He is everything, and everything is for Him. Let us read these verses and see what they unfold of the immeasurable Christ. “He who comes from above is above all; he who is of the earth is of the earth and speaks of the earth. He who comes from heaven is above all. What He has seen and heard, of this He testifies, and no one receives His testimony. He who receives His testimony has sealed that God is true. For He whom God has sent speaks the words of God, for He gives the Spirit not by measure.
