In the encounter between Nicodemus and Jesus in John 3 we see a picture of God as loving humanity and welcoming them into the light of full and eternal life. We find that Jesus is confronting Nicodemus' legalistic religion with the love and acceptance of the Father. Finally, we see that by the Spirit we have been given the right (ie - power) to become children of God and no longer need to feel the need to prove ourselves to man or God.
