John expands on being born again in his letters:
- 1 John 5:1 – "Everyone who believes that Jesus is the Christ has been born of God."
- 1 John 2:29 – "If you know that He is righteous, you may be sure that everyone who practices righteousness has been born of Him."
- 1 John 3:9 – "No one born of God makes a practice of sinning, for God's seed abides in him."
This means, as Jesus also taught in John 8, we are born again by believing Jesus is the Christ (in John 8, the light of the world, sent by the Father), keeping within us the teachings of Jesus, God’s holy seed, then practicing righteousness and not sin, by freedom from sin from knowledge of the truth, from Jesus.
