Have you changed the title? (John 3:1-15)
Nicodemus says to Jesus, "Rabbi, we know that you are a teacher who came from God." Nicodemus is well aware that Jesus performed many miracles in Jerusalem during the Passover. We know of the incident where water was made into wine in Ghana. He is recognized as one of the many prophets who performed miracles in the Old Testament. But Nicodemus said that he knew that Jesus was a teacher who came from God, but revealed that he knew nothing about Jesus. I know Jesus as a former prophet or a teacher who works miracles. Rather, Jesus Himself knows everyone and what is inside of them (John 2:24-25). Jesus knows everything about human beings. Knowing everything, you can solve human problems. Jesus knows everything about Nicodemus, who came late. What Nicodemus knows is but a sign. You cannot possess the kingdom of heaven as a target. The target disappears over time.
A believer cannot confess that Jesus is Lord without the experience of being born again. It is even more impossible to obey the word of the Lord. Unless a believer is born again, he cannot experience or enter the kingdom of God. Believers must bear the beautiful fruit of the Holy Spirit and glorify God. For a believer to have eternal life, it is to live the rest of their lives with Christ. Such people are living in the kingdom of God under the rule of God. The kingdom of God has already come.
