John 3:4-5

John 3:4-5. Nicodemus saith unto him, How can a man be born when he is old? can he enter the second time into his mother’s womb, and be born? Jesus answered, Verily, verily, I say unto thee, Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God.

If the "water" mentioned here relates to baptism,-which I greatly question,-then, certainly, it shows the way of entrance for a believer, publicly, into the kingdom of God. But if it relates to the purifying power of the Spirit of God,-as I believe it does,-then it teaches us that no man enters into the kingdom of God, and becomes a partaker of its privileges,-which is something more than merely seeing it,-except the Spirit of God shall be to him as water purifying him from sin. This is the reason why a man cannot enter into the spiritual kingdom until he is born again, born from above.
