In this passage Nicodemus, a respected religious leader comes to Jesus by night to discuss his identity. Jesus's response teaches us one of the most fundamental truths of Christianity: we must be born again or we cannot see the Kingdom of God. What does Jesus mean by this? How is one born again? What does this have to do with each one of us? This new birth is a miracle of God wrought in us by his Spirit. Reflecting on the doctrine of regeneration leads us to gratitude for the gift of salvation.
