The effects of this unbelief on our Lord were twofold. It limited His power. Matthew says that 'He did not many mighty works.' Mark goes deeper, and boldly days 'He could not.' It is mistaken jealousy for Christ's honour to seek to pare down the strong words. The atmosphere of chill unbelief froze the stream. The power was there, but it required for its exercise some measure of moral susceptibility. His miraculous energy followed, in general, the same law as His higher exercise of saving grace does; that is to say, it could not force itself upon unwilling men. Christ 'cannot' save a man who does not trust Him. He was hampered in the outflow of His healing power by unsympathetic disparagement and unbelief. Man can thwart God. Faith opens the door, and unbelief shuts it in His face. He 'would have gathered,' but they 'would not,' and therefore He 'could not.'
The second effect of unbelief on Him was that He 'marvelled.' He is twice recorded to have wondered--once at a Gentile's faith, once at His townsmen's unbelief. He wondered at the first because it showed so unusual a susceptibility; at the second, because it showed so unreasonable a blindness. All sin is a wonder to eyes that see into the realities of things and read the end; for it is all utterly unreasonable (though it is, alas! not unaccountable) and suicidal. 'Be astonished, O ye heavens, at this.' Unbelief in Christ is, by Himself, declared to be the very climax of sin, and its most flagrant evidence (John xvi. 9); and of all the instances of unbelief which saddened His heart, none struck more chill than that of these Nazarenes. They had known His pure youth; He might have reckoned on some touch of sympathy and predisposition to welcome Him. His wonder is the measure of His pain as well as of their sin.
Nor need we wonder that He wondered; for He was true man, and all human emotions were His. To one who lives ever in the Father's bosom, what can seem so strange as that men should prefer homeless exposedness and dreary loneliness? To one whose eyes ever behold unseen realities, what so marvellous as men's blindness? To one who knew so assuredly His own mission and rich freightage of blessing, how strange it must have been that He found so few to accept His gifts! Jesus knew that bitter wonder which all men who have a truth to proclaim which the world has not learned, have to experience--the amazement at finding it so hard to get any others to see what they see. In His manhood, He shared the fate of all teachers, who have, in their turn, to marvel at men's unbelief.
II. The new instrument which Christ fashions to cope with unbelief. What does Jesus do when thus 'wounded in the house of His friends'? Give way to despondency? No; but meekly betake Himself to yet obscurer fields of service, and send out the Twelve to prepare His way, as if He thought that they might have success where He would fail. What a lesson for people who are always hankering after conspicuous 'spheres,' and lamenting that their gifts are wasted in some obscure corner, is that picture of Jesus, repulsed from Nazareth, patiently turning to the villages! The very summary account of the trial mission of the Twelve here given presents only the salient points of the charge to them, and in its condensation makes these the more emphatic. Note the interesting statement that they were sent out two-and-two. The other Evangelists do not tell us this, but their lists of the Apostles are arranged in pairs. Mark's list is not so arranged, but he supplies the reason for the arrangement, which he does not follow; and the other Gospels, by their arrangement, confirm his statement, which they do not give. Two-and-two is a wise rule for all Christian workers. It checks individual peculiarities of self-will, helps to keep off faults, wholesomely stimulates, strengthens faith by giving another to hear it and to speak it, brings companionship, and admits of division of labour. One-and-one are more than twice one.
