NOTES for Luk 7:18-35
Why does John, who himself bore witness to Jesus and saw the Spirit descending upon Him, suddenly send his disciples to Him with such a question? Perhaps he wants to strengthen his disciples' faith? Or perhaps in prison he himself was passing through the final trials of faith?
In any case, this question is extraordinarily important for us: “Art Thou He that should come?” We are called not merely to “believe” but to take a very decisive step—to take up the cross and follow Him. To do so, we must be certain that this is indeed He.
Jesus answers in the words of a messianic prophecy: let John's disciples judge by the works He performs. It seems that nothing else is left for us either: to look at what He does in our lives and in the lives of people we know, and to draw the right conclusions.
