What does John 3:2 mean?
Nicodemus was an important person in his culture. He was a respected Pharisee, a knowledgeable teacher, and a member of the Sanhedrin court. By the time of Jesus' death, Nicodemus seems to be one of His supporters (John 19:39–42). For now, though, he approaches Christ under cover of night. This might have been out of fear that he would be seen asking questions of Jesus. It's also possible that Nicodemus wanted to speak to Jesus without the distraction of a large crowd.Addressing Jesus as "Rabbi" was a gesture of respect. Nicodemus would have been called "Rabbi" by others, as well. This suggests that Nicodemus sees himself and Jesus as equals, at least at first. Jesus will humble Nicodemus during the conversation, showing him that he doesn't understand spirituality as well as he thinks he does (John 3:10). The gospel of John presents Jesus' miracles as proof that He has divine power. Nicodemus recognizes this; he interprets Jesus' abilities as a sign that God sent Him. However, he still has questions about Jesus' teachings.
