John 3:5-8 (NCV): "But Jesus answered, "I tell you the truth, unless one is born from water and the Spirit, he cannot enter God’s kingdom. Human life comes from human parents, but spiritual life comes from the Spirit. Don’t be surprised when I tell you, “You must all be born again.” The wind blows where it wants to and you hear the sound of it, but you don’t know where the wind comes from or where it is going. It is the same with every person who is born from the Spirit.“

John 16:7-11 (NCV): “But I tell you the truth, it is better for you that I go away. When I go away, I will send the Helper to you. If I do not go away, the Helper will not come. When the Helper comes, he will prove to the people of the world the truth about sin, about being right with God, and about judgment. He will prove to them that sin is not believing in me. He will prove to them that being right with God comes from my going to the Father and not being seen anymore. And the Helper will prove to them that judgment happened when the ruler of this world was judged.”
