Born of water and born of spirit
What do you think of a person, who has received the Holy Spirit of God and has put his faith and trust in the Lord Jesus? (Acts, 10:43-48) Has he or she been born again from above by the spirit of God or not? (John, 3:3-8) Or has he or she not yet started a new life as a Christian, and will not start a new life before he or she will be immersed in the water? What does it mean, when the Lord said:
"...unless one is born again, he cannot see the kingdom of God..."
"Most assuredly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. "That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. "Do not marvel that I said to you, 'You must be born again.' "The wind blows where it wishes, and you hear the sound of it, but cannot tell where it comes from and where it goes. So is everyone who is born of the Spirit." (John 3:3, 5-8)
There have been six main theories of what Jesus meant by these words. The most promising of them are that [1] he spoke of two different births, one natural (of water/ of flesh) and one supernatural (of the Spirit) or [2] that he was referring to the spiritual birth by the Spirit with a parallel phrase "of water and of the spirit" (Isa, 44:3-5, Eze, 36:25-26).
One interpretation is that Jesus is referring to "the word of God" by "water", but I do not find this interpretation consistent enough.
