John 3 presents a profound conversation between Jesus and Nicodemus, a Pharisee and member of the Jewish ruling council. Nicodemus visits Jesus by night, acknowledging His divine authority. Jesus tells Nicodemus that to enter the kingdom of God, one must be born again, not physically but spiritually, through the water and the Spirit. He explains that God sent His Son into the world to save it, and those who believe in Him will have eternal life.
Jesus compares Himself to the bronze serpent that Moses lifted up in the wilderness, saying that just as those who looked upon it were saved, so too will those who believe in Him be saved from eternal death. He emphasizes God's love for the world, stating that the Son was sent not to condemn but to save.
Further, Jesus reveals that light has come into the world, but people love darkness because their deeds are evil. He encourages people to come to the light, exposing their actions to God's truth. Jesus also shares that only those who believe in Him will have everlasting life, while those who reject Him will face God's judgment.
