John 3:4-6

The mode of regeneration: V. 4. 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?

V. 5. 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. V. 6. That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.

The statement of Jesus, simple as it was, was at the same time so thoroughly at variance with the commonly accepted idea as to the way of getting to heaven that it almost took the Pharisee's breath. His question reveals his utter inability to grasp the idea of the Lord to its full extent. He knew, of course, that a physical rebirth was impossible. He understood that Christ's reference was to a spiritual transformation.

But just such a change in the field of morality seemed to him impossible, verging on the ridiculous, preposterous. How can a person, especially one of advanced years, deny the habits and customs of years? If that is to be done, then every person must really begin his life allover again, just as he came into the world. The very suggestion is unthinkable from the standpoint of reason, just as the idea of conversion, of regeneration, is preposterous in the opinion of the average self-righteous person.

And therefore Jesus explains, once more with solemn emphasis, that the rebirth out of water and Spirit is absolutely essential, it is a prime prerequisite, for the entering into the kingdom of heaven. Spiritual regeneration by Baptism, through which the Spirit of God is given, is unavoidably necessary. Baptism is the means by which the Holy Spirit works regeneration, the new birth.

Conversion is therefore in no way the work of man, but it is the work of God the Holy Ghost. To be born again or anew is to be born out of the Spirit, to receive from Him a new heart, a new mind, a new will. To gain this object, God uses Baptism as one of His instruments. This Sacrament actually works and gives new life; the water is not merely a symbol, but an actual means, through the power of the Word, in working salvation. But one that has been converted in this way, and has thus become a partaker of the grace of God, thereby enters into the kingdom of heaven, into the invisible Church; for the kingdom of God and the kingdom, of heaven are identical.

That this demand of an absolute regeneration is well founded is proved by the fact that all men, as they are born into the world, are flesh; theirs is a sinful, corrupted nature, alienated from God, hostile to God. The carnal-mindedness of natural man is enmity toward God. It is an irreconcilable contrast: all men carnally born, from carnal parents, by nature flesh and filled with the same sinful affections as the parents in their nature, and, on the other hand, that which comes into existence by the creative work of the Spirit in conversion, the new man, filled with divine life, with divine power from above, through the working of the Spirit. He that is born of the Spirit has the Spirit's manner; his heart, mind, and will are directed to God and to that which pertains to God; such a one, and he only, is fit for the kingdom of God; he alone can receive the kingdom of God with its heavenly gifts and blessings.
