The things Jesus is saying don't make sense, and he wants to know more. We don't know what motivated him, but we do know he chose a beautiful response: seeking more information.
Of course, Jesus gives him answers that only continue the confusion. To see the kingdom of God, one most be born anew, of water and the spirit. Though the idea of being "born again" isn't startling to us, it hadn't acquired the baggage we've heaped on it yet when Jesus said it to Nicodemus. And it's a crazy idea: finding a new identity, nurtured and blessed as if we had been in the life-giving power of God's own womb.
Last week, we went with Jesus to the wilderness, and began to thirst with him. This week, we receive assurance that we are surrounded by the life-giving waters of God. Though they just might make us new people.
