[Lera]

Joh 3:5 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.
Joh 3:6 That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.

That is too simple, to straight forward, to obvious for the folks looking for escape clauses, like nearly all catholic apologists we see on these threads. You see what Jesus answered when Nicodemus tried to wiggle out with his reference to entering again into his mother's womb. Jesus stated flatly, 'that which is born of flesh is flesh.' Clearly, the born of water refers to born of flesh.

You can show them over and over, and they have such pride-filled willful blindness that it will not penetrate, and they rush to support each other in the errors and ridicule those who offer them The Truth.
