When Jesus is referring to being born physically, and says, *born of water*, it only makes sense that it refers to physical birth.
If He meant baptism, that would have been the perfect time to say so.
And He didn’t.
Understanding this was an eyeopener for me. I remember the sermon well when that sunk in. I went home and studied the scriptures on the matter. All the scriptures surrounding that conversation confirmed to me Jesus ment physical Birth.
Though I didn’t believe Baptism saves, and do not now....my reason , at the time I was Batized was simple...I wanted to follow Jesus...and He was baptised. Such simple unclutered faith then...but then He sends us to school...:)
