@EdJ Hi Ed,
CONTEXT.
Jn 3.3
..unless one is born AGAIN, he cannot see the kingdom of God.
JN 3.7
You must be BORN AGAIN.
These verses confirm that Jesus is not speaking of natural birth but rebirth.

And the rebirth is of God by His Spirit
JN 3.8
So it is with everyone who is BORN OF THE SPIRIT
Jn 1.13
Those who were born, not of blood, not of the will of the flesh, nor of the will of man BUT OF GOD.
1 Jn 5.9
No one who is born of God practices sin.

All have sinned, all need the forgiveness of God, the washing before the anointing.

Return to Peter at Pentecost and and 1 Peter 3 and see the forgiveness requires repentance and water baptism
