Alert, this is a little political: In our divisive politics today, "born again" is sometimes used disdainfully. Often by politicians who are trying to figure out which way the wind is blowing.

John 3:5-8
Jesus answered, “Most assuredly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God.
That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.
Do not marvel that I said to you, ‘You must be born again.’
The wind blows where it wishes, and you hear the sound of it, but cannot tell where it comes from and where it goes. So is everyone who is born of the Spirit.”
