 verse 19, summons two of them, sends them to the Lord saying, here's the question, are you the expected one or do we look for someone else? It's like saying, are you the Messiah? Are you the one promised in the Old Testament? And at that point, we are now coming face to face with John's doubts. What created those doubts? What caused him to doubt what he believed? Why is he saying, Lord, I believe, help my unbelief?
