I. We do not believe that this message of John's was sent for the sake of strengthening his disciples' faith in Jesus as Messiah, nor that it was merely meant as a hint to Jesus to declare Himself. The question is John's. The answer is sent to him: it is he who is to ponder the things which the messengers saw, and to answer his own question thereby. The note which the evangelist prefixes to his account gives the key to the incident. John was 'in prison,' in that gloomy fortress of Machaerus which Herod had rebuilt at once for 'a sinful pleasure-house' and for an impregnable refuge, among the savage cliffs of Moab. The halls of luxurious vice and the walls of defence are gone; but the dungeons are there still, with the holes in the masonry into which the bars were fixed to which the prisoners--John, perhaps, one of them--were chained. No wonder that in the foul atmosphere of a dark dungeon the spirit which had been so undaunted in the free air of the desert began to flag; nor that even he who had seen the fluttering dove descend on Christ's head, and had pointed to Him as the Lamb of God, felt that 'all his mind was clouded with a doubt.' It would have been wiser if commentators, instead of trying to save John's credit at the cost of straining the narrative, had recognised the psychological truth of the plain story of his wavering conviction and had learned its lessons of self-distrust. There is only one Man with whom it was always high-water; all others have ebbs and flows in their religious life, and variations in their grasp of truth. The narrative further gives the motive for John's embassy, in the report which had reached him of 'the works of Christ.' We need only recall John's earlier testimony to understand how these works would not seem to him to fill up the role which he had anticipated for Messiah. Where is the axe that was to be laid at the root of the trees, or the fan that was to winnow out the chaff? Where is the fiery spirit which he had foretold? This gentle Healer is not the theocratic judge of his warning prophecies. He is tending and nurturing, rather than felling, the barren trees. A nimbus of merciful deeds, not of flashing 'wrath to come,' surrounds His head. So John began to wonder if, after all, he had been premature in his recognition. Perhaps this Jesus was but a precursor, as he himself was, of the Messiah. Evidently he continues firm in the conviction of Christ's being sent from God, and is ready to accept His answer as conclusive; but, as evidently, he is puzzled by the contrariety between Jesus' deeds and his own expectations. He asks, 'Art Thou _He that cometh_'--a well-known name for Messiah--'or are we to expect another?' where it should be noted that the word for 'another' means not merely a second, but a different kind of, person, who should present the aspects of the Messiah as revealed in prophecy, and as embodied in John's own preaching, which Jesus had left unfulfilled.
