Believing in Jesus is the only way to heaven, because he alone died for our sins and made us right before God. Living his way may not be popular, but it is true and right. The wind blows wherever it pleases. You hear its sound, but you cannot tell where it comes from or where it is going. So it is with everyone born of the Spirit.
Salvation is a work done in our life by the Holy Spirit.
Jesus explained that we cannot control the work of the Holy Spirit. He works in ways we cannot predict or understand. Just as you did not control your physical birth, so you cannot control your spiritual birth. Salvation is much more than just knowing about Jesus. This Jewish teacher of the Bible knew the Old Testament thoroughly, but he didn t understand what it said about the Messiah.
