John 3:5-6
“Jesus answered, ‘Very truly I tell you, no one can enter the kingdom of God unless they are born of water and the Spirit. Flesh gives birth to flesh, but the Spirit gives birth to spirit.’”
With this verse Jesus lays down a gauntlet. (In olden days, to ‘throw down the gauntlet’ was to challenge someone to a duel … often to the death.) Here he literally spells out a challenge that means the difference between life and death.
Q: How do you understand the meaning of, “Flesh gives birth to flesh, but the Spirit gives birth to spirit?”
