Born Again is Old Testament
Jesus told Nicodemus you must be born again in John 3:1-10.
1,930 years later it became the Christian buzz word of the century.
People treat the phrase 'Born Again' as a New Testament teaching. Nothing could be farther from the truth... except you need to repent of your sins to be saved is a further from the truth.
Born Again, According to Wikipedia is,"The term born again has become widely associated with the evangelical Christian renewal since the late 1960s, first in the United States and then around the world." Wiki also says "Born again, or to experience the new birth, is a phrase, particularly in evangelicalism, that refers to a "spiritual rebirth", or a regeneration of the human spirit."
Jesus told Nicodemus except a man be born again, he cannot see the kingdom of God. Nicodemus asked Jesus how could these things be? Jesus said you are a master of Israel and you do not know?
Nicodemus, a pharisee, a master of the Israel, a religious leader of the Jews should have known... You must be born again.
Born again is an Old Testament teaching NOT a New Testament teaching.
Jesus said And as Moses lifted up the serpent in the wilderness...
Why did Jesus say that? Because the only thing the children of Israel had to do is believe God and they were saved.
Look and Live, that is salvation. Moses... go create a serpent, an idol, something God's hates and put it on a pole and tell the people if they will look at the serpent they will live.
So must the son of man be lifted up, that whosoever believeth on Him should not perish but, have eternal life. For God so loved the world that he gave his only begotten son that whosoever believeth in him should not perish but, have everlasting life.
Whoever looks to Jesus for salvation will live.
Old Testament Jews who believed God were Born Again. That is what Jesus said.
