The distinguished Jewish theologian could no longer deny the miraculous power of God at work in the life and ministry of the Galilean. Nor could he quench his thirst to meet Jesus face to face. So, humbling himself and putting his reputation on the line, Nicodemus went one night to confess that Jesus was from God and inquire of Him the way of salvation.
Jesus responded to Israel’s prominent thinker by making an issue of the supernatural work of the Holy Spirit. No one can enter the kingdom of God without a spiritual transformation, Jesus explained, and this requires the Spirit of God to bring about the miracle of regeneration. Just as a natural birth is necessary for one to enter and become aware of the human family, we must be born again, born of the Spirit—in order to grasp the reality and relationships of the kingdom of God. Furthermore, admission to the kingdom of God is never by the proud prerogative of race, status, nation, class, or gender. It is certainly not by heredity! All who enter the kingdom of God must be born into it by the Spirit. This spiritual birth is an act of God.
Jesus was faithful to explain to Nicodemus the one simple condition for being born again: believing in God’s one and only Son who was lifted up (crucified) for our sins (John 3:14-21). The evidence that one has truly believed (come into the light), Jesus said, is that he lives by the truth (John 3:21).
