I have spent 63 years of my life surrounded by deeply religious people of the Christian Faith. I attended Sabbath School until I was 25 years old. I have taken Bible Studies from a couple of denominations, and taken History of the Old Testament class in College. But I have never heard a person use this "Born Again" term until I listened to TV evangelists. I have never heard it from my family, or from my Morman friends, or Lutheran friends, or from members of "The Brethren".
THAT shows you & anyone reading this how MANY Denominations of “Christianity”
are NOT Christians. Not being critical, seriously. Read the next quote.
John 3:1-24 is a conversation between Jesus and Nicodemus (includes John3:16.) Jesus came up with the phrase, not the American 70's!
Verse 7, Jesus said, “ Ye must be born again”
+/- 2000 years ago. Don’t believe me. Believe Jesus.
