What does John 3:11 mean?
One reason people do not understand is because they will not understand. In other words, the problem is not a lack of evidence, or a lack of reason, but a lack of interest. Knowing the truth is different from submitting to the truth. The Pharisees (John 3:1) know quite a bit about the Old Testament, but they won't submit to the authority of Christ. Jesus was described in John 1:1 as "the Word," from the Greek term logos. Jesus is the living message of God, and what He says comes from God. Nicodemus recognizes this in Jesus' miracles (John 3:2), but he is still having a hard time seeing the truth. His legalism and traditions are getting in the way.Here again, Jesus repeats the word amen which has been kept mostly intact into modern speech. The term means "believe," or "surely," and is usually used after saying something a person sincerely hopes to be true. This is why we respond with "amen" to something we strongly agree with. Using it at the beginning of a statement implies that the person speaking has first-hand knowledge: they are not relying on anyone else for it. It's a strong claim of knowledge and authority.
