Jesus answered and said to him..."Truly, truly, I say to you, we speak that which we know, and bear witness of that which we have seen; and you do not receive our witness. If I told you earthly things and you do not believe, how shall you believe if I tell you heavenly things?"
"And no one has ascended into heaven, but He who descended from heaven, even the Son of Man. And as Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up: that whoever believes may in Him have eternal life."
"And this is the judgement, that the light is come into the world, and men loved the darkness rather than the light; for their deed were evil. For everyone who does evil hates the light, and does not come into the light, lest his deeds should be exposed."
"But he who practices the truth comes to the light,that his deeds may be manifested as having been wrought in God." John 3: 10, 11-15, 19-21
