Jesus discussed the new birth in His conversation with Nicodemus, a Jewish leader, in John 3. Jesus said to him, “Very truly I tell you, no one can see the kingdom of God unless they are born again” (John 3:3). Nicodemus was puzzled and asked how anyone could re-enter his mother’s womb and be born a second time. Jesus doubled down: “Very truly I tell you, no one can enter the kingdom of God unless they are born of water and the Spirit” (verse 5). Then He expounded on what the new birth is.
