Jesus said unto him, If them canst believe, all things are possible to him that believeth.'--Mark ix. 23.
The necessity and power of faith is the prominent lesson of this narrative of the healing of a demoniac boy, especially as it is told by the Evangelist Mark, The lesson is enforced by the actions of all the persons in the group, except the central figure, Christ. The disciples could not cast out the demon, and incur Christ's plaintive rebuke, which is quite as much sorrow as blame: 'O faithless generation I how long shall I be with you? how long shall I suffer you?' And then, in the second part of the story, the poor father, heart-sick with hope deferred, comes into the foreground. The whole interest is shifted to him, and more prominence is given to the process by which his doubting spirit is led to trust, than to that by which his son is healed.
There is something very beautiful and tender in Christ's way of dealing with him, so as to draw him to faith. He begins with the question, 'How long is it ago since this came unto him?' and so induces him to tell all the story of the long sorrow, that his burdened heart might get some ease in speaking, and also that the feeling of the extremity of the necessity, deepened by the very dwelling on all his boy's cruel sufferings, might help him to the exercise of faith. Truly 'He knew what was in man,' and with tenderness born of perfect knowledge and perfect love, He dealt with sore and sorrowful hearts. This loving artifice of consolation, which drew all the story from willing lips, is one more little token of His gentle mode of healing. And it is profoundly wise, as well as most tender. Get a man thoroughly to know his need, and vividly to feel his helpless misery, and you have carried him a long way towards laying hold of the refuge from it.
How wise and how tender the question is, is proved by the long circumstantial answer, in which the pent-up trouble of a father's heart pours itself out at the tiny opening which Christ has made for it. He does not content himself with the simple answer, 'Of a child,' but with the garrulousness of sorrow that has found a listener that sympathises, goes on to tell all the misery, partly that he may move his hearer's pity, but more in sheer absorption with the bitterness that had poisoned the happiness of his home all these years. And then his graphic picture of his child's state leads him to the plaintive cry, in which his love makes common cause with his son, and unites both in one wretchedness. 'If thou canst do anything, have compassion on _us_ and help _us_.'
Our Lord answers that appeal in the words of our text. There are some difficulties in the rendering and exact force of these words with which I do not mean to trouble you. We may accept the rendering as in our Bible, with a slight variation in the punctuation. If we take the first clause as an incomplete sentence, and put a break between it and the last words, the meaning will stand out more clearly: 'If thou canst believe--all things are possible to him that believeth.' We might paraphrase it somewhat thus: Did you say 'If thou canst do anything'? That is the wrong 'if.' There is no doubt about that. The only 'if' in the question is another one, not about me, but about you. 'If _thou_ canst believe--' and then the incomplete sentence might be supposed to be ended with some such phrase as 'That is the only question. If thou canst believe--all depends on that. If thou canst believe, thy son will be healed,' or the like. Then, in order to explain and establish what He had meant in the half-finished saying, He adds the grand, broad statement, on which the demand for the man's faith as the only condition of his wish being answered reposes: 'All things are possible to him that believeth.'
