Nicodemus was a religious leader, but wasn't understanding what God was trying to tell him. Those of us who know Jesus as our savior, know that religion has nothing to do with it. Nicodemus came to Jesus by night because he was afraid to be seen with him. He acknowledged that Jesus was from God, called him a Rabbi and a teacher. He knew that Jesus was a good teacher. We were born sinners, we need to be born again, accepting Jesus as our savior. Repenting of our sins and asking Him in our hearts.
