9. Nicodemus answered by asking, How can all this be possible?
10. Jesus replied, Are you the teacher of Israel, and yet do not know nor understand these things? [Are they strange to you?]
11. I assure you, most solemnly I tell you, We speak only of what we know [we know absolutely what we are talking about]; we have actually seen what we are testifying to [we were eyewitnesses of it]. And still you do not receive our testimony [you reject and refuse our evidence–that of Myself and of all those who are born of the Spirit].
12. If I have told you of things that happen right here on the earth and yet none of you believes Me, how can you believe (trust Me, adhere to Me, rely on Me) if I tell you of heavenly things?
13. And yet no one has ever gone up to heaven, but there is One Who has come down from heaven–the Son of Man [Himself], Who is (dwells, has His home) in heaven.
14. And just as Moses lifted up the serpent in the desert [on a pole], so must [so it is necessary that] the Son of Man be lifted up [on the cross], [Num. 21:9.]
15. In order that everyone who believes in Him [who cleaves to Him, trusts Him, and relies on Him] may not perish, but have eternal life and [actually] live forever!
