In the early part of John’s Gospel, Jesus has a conversation with Nicodemus, a Jewish leader who questions Jesus’ authority. Jesus answers him, making it clear that being “born again” is necessary in order to see the kingdom of God. Alistair Begg reminds us that the new birth of which Jesus spoke is essential and supernatural—a miraculous and mysterious work of Almighty God that brings about a complete change of heart and gives the believer a new family, a new identity, and a new mentality.
