Nicodemus was a Jewish leader and member of the Pharisees. He came to Jesus secretly at night and said “Teacher, we know that God has sent you as a teacher, because only those who God is with can do the signs you have performed.”
Jesus told him, “Truly I say to you, unless you have been reborn, you can never enter into the kingdom of God.”
“How can anyone be born again?” Nicodemus exclaimed. “How can an old person enter his mother’s womb and be born a second time?”
“This is the truth – Unless you are born by the way of water and of the Holy Spirit, you will never enter the kingdom of God. Whoever is born by the way of the flesh is just flesh, but if you are born by the way of the Spirit, you are so much more. Don’t be amazed when I tell you that you must be born a second time. You can hear the wind blow but you don’t know where it came from or where it will go. The same is true of everyone who is born by the way of the Spirit.”
“How is this possible?” asked Nicodemus.
“You, a respected teacher of the Law of Moses, and you don’t understand this? Truly, I’m telling you what God reveals to me, but you don’t accept it. If you don’t believe me when I tell you about the earthly things that happen, then how will you believe me when I tell you about heavenly things? The only one who has been raised up into heaven is the same one who came down from heaven, and that is the Son of Man. In the same way that Moses raised up an image of a serpent to heal people in the wilderness, the Son of Man must be raised up, so that everyone who believes in him will be saved from death.
God loves the world so much that he gave his only Son, so that whoever believes in him will not die but have eternal life. God didn’t send his Son here to condemn the world, but that the world might be saved because of him. Anyone who believes in him is saved, but those who don’t believe are lost, because they don’t believe in the only Son of God.
Those who are lost have made themselves that way, because the Light has come into the world and they loved the darkness more because they did evil things. Everyone who does evil things hates to have them exposed to the Light. But everyone who lives truthfully comes to the Light so that God’s glory may be revealed.”
