The reply Jesus gave has been interpreted in a very vague way, to support the notion of water baptism. But what Jesus did do was go to where Nic's brain was focused and bring him along to a greater meaning. If you would like to read the exchange it can be found in John Chapter three, before the much quoted John 3:16. I believe the water Jesus refers to in John 3 is the placental water from which we are born into the air world ... but there is no mistaking when Jesus says you must be born of the Spirit, too. And He made it as simple as saying 'Thank you, Lord, and accepting the Grace of God in Christ as His gift to you if you will believe on Him..'
OK, thank you much.
AMEN!!!
