Christ's baptism at the Jordan River was one - water and spirit. That is the example we follow. Christ said, you must have both water and spirit to enter the Kingdom of Heaven.
Again, the scripture in John 3 is about "birth". The context of the discussion between Jesus and Nicodemus is birth!
You are taking a discussion about being "born again" and assuming, because of your mindset that Jesus is talking about baptism.
Where is the word baptism in this discussion? Does that mean anything to you? John 3:1-8
1 There was a man of the Pharisees named Nicodemus, a ruler of the Jews. 2 This man came to Jesus by night and said to Him, "Rabbi, we know that You are a teacher come from God; for no one can do these signs that You do unless God is with him." 3 Jesus answered and said to him, "Most assuredly, I say to you, unless one is born again, he cannot see the kingdom of God." 4 Nicodemus said to Him, "How can a man be born when he is old? Can he enter a second time into his mother's womb and be born?" 5 Jesus answered, "Most assuredly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. 6 That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. 7 Do not marvel that I said to you, 'You must be born again.' 8 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."
That which is born of the flesh is flesh... What do you think this means. It is speaking of natural child birth! BORN OF FLESH! That is being born of water!
Your method of interpretation is scary. You just make up the rules as you go!
There is no telling what other things you have come up with!
Goodby!
