Everybody has been born once, but being born an additional time didn’t make sense to Nicodemus (John 3). Being “born again” is a common religious term, which might be regarded something like having a membership to the Christian Country Club.
Saying “I’m born again” can be synonymous with “I’m a Christian,” which should mean, “I’m not the person I used to be. I’m Christ-like.”
Jesus told Nicodemus that entrance into the Kingdom of God was impossible without being born of the Spirit (John 3:5). Self-righteous Jews claimed to be children of Abraham, but Jesus said they were children of their father the devil (John 8:39, 44).
Does being born again mean we acquire a new spirit like unto God, which allows us to claim God as our Father?
