Mark - Matthew 11

Does John the Baptist have doubts of who Jesus is?(v3)"Are you really the one we are waiting for, or shall we keep on looking?" John baptized Jesus with the knowledge of who He was, so why the question? Again Jesus reiterates-FOLLOW ME! Even after all the miracles the masses aren't getting the significance of what He is trying to freely give them. He says children know the secret to faith but the wise think they have all the answers. I think I have all the answers more times than not. Please help me do more listening today Lord.
