11 For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God.using scripture with your thoughts also. what doe being Born again mean to you . Nicodemus had a hard time understanding and if we are honest its better experienced than explained . Born of the spirit and the water me personally i feel the water represents the word . due to the fact we are told faith comes by hearing and hearing by the word of God
12 Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God.
13 Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.
14 But the natural man receiveth not the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned.
15 But he that is spiritual judgeth all things, yet he himself is judged of no man.
16 For who hath known the mind of the Lord, that he may instruct him? but we have the mind of Christ.
1 Cor 2:11-16
