Jesus answered him, "Most assuredly, I tell you, unless one is born anew,{The word translated "anew" here and in John 3:7 (anothen) also means "again" and "from above".} he can't see the Kingdom of God."
First, None but Christ was able to reveal to us the will of God for our salvation. Nicodemus addressed Christ as a prophet; but he must know that he is greater than all the Old-Testament prophets, for none of them had ascended into heaven. They wrote by divine inspiration, and not of their own knowledge; see John 1:18. Moses ascended into the mount, but not into heaven. No man hath attained to the certain knowledge of God and heavenly things as Christ has; see Matthew 11:27. It is not for us to send to heaven for instructions; we must wait to receive what instructions Heaven will send to us; see Proverbs 30:4 Deuteronomy 30:12.
