Did Nicodemus know about baptism? Did Nicodemus know about child birth? Jesus spoke to him about what he knew not what he did not know. Why do you suppose Nicodemus talks about going back into his mothers womb? He knew Jesus was speaking of child birth.....not baptism. Born of flesh.....remember. Born of spirit.....remember. YOU MUST BE BORN AGAIN.....How? Spiritually!!!Evangelicals claim that one is born again at the first moment of faith in Christ. According to this theory, faith in Christ produces regeneration. The Calvinist position is the reverse: Regeneration precedes and produces faith in Christ. Calvinists (some of whom also call themselves Evangelicals) suppose that God "secretly" regenerates people, without their being aware of it, and thiscauses them to place their faith in Christ.
To defend these theories, Evangelicals and Calvinists attempt to explain away the many unambiguous verses in the Bible that plainly teach baptismal regeneration. One strategy is to say that the water in John 3:5 refers not to baptism but to the amniotic fluid present at childbirth. The absurd
implication of this view is that Jesus would have been saying, "You must be born of amniotic fluid and the Spirit." A check of the respected Protestant Greek lexicon, Kittels Theological Dictionary of the New Testament, fails to turn up any instances in ancient, Septuagint or New Testament Greek where "water" (Greek: hudor) referred to anything like "amniotic fluid" (VIII:314333).
Born twice die once........Born once die twice.
See if you can figure it out.
