8 Only God's Spirit gives new life. The Spirit is like the wind that blows wherever it wants to. You can hear the wind, but you don't know where it comes from or where it is going.
9 “How can this be?” Nicodemus asked.
10 Jesus replied:How can you be a teacher of Israel and not know these things?
11 I tell you for certain that we know what we are talking about because we have seen it ourselves. But none of you will accept what we say.
12 If you don't believe when I talk to you about things on earth, how can you possibly believe if I talk to you about things in heaven?
13 No one has gone up to heaven except the Son of Man, who came down from there.
14 And the Son of Man must be lifted up, just as that metal snake was lifted up by Moses in the desert.
