III. Notice the cry of infant faith.
'Help Thou mine unbelief' may have either of two meanings. The man's desire was either that his faith should be increased and his unbelief 'helped' by being removed by Christ's operation upon his spirit, or that Christ would 'help' him and his boy by healing the child, though the faith which asked the blessing was so feeble that it might be called unbelief. There is nothing in the language or in the context to determine which of these two meanings is intended; we must settle it by our own sense of what would be most likely under the circumstances. To me it seems extremely improbable that, when the father's whole soul was absorbed in the healing of his son, he should turn aside to ask for the inward and spiritual process of having his faith strengthened. Rather he said, 'Heal my child, though it is unbelief as much as faith that asks Thee to do it.'
The lesson is that, even when we are conscious of much tremulousness in our faith, we have a right to ask and expect that it shall be answered. Weak faith _is_ faith. The tremulous hand _does_ touch. The cord may be slender as a spider's web that binds a heart to Jesus, but it _does_ bind. The poor woman in the other miracle who put out her wasted finger-tip, coming behind Him in the crowd, and stealthily touching the hem of His garment, though it was only the end of her finger-nail that was laid on the robe, carried away with her the blessing. And so the feeblest faith joins the soul, in the measure of its strength, to Jesus Christ.
But let us remember that, whilst thus the cry of infant faith is heard, the stronger voice of stronger faith is more abundantly heard. Jesus Christ once for all laid down the law when He said to one of the suppliants at His feet, 'According to your faith be it unto you.' The measure of our belief is the measure of our blessing. The wider you open the door, the more angels will crowd into it, with their white wings and their calm faces. The bore of the pipe determines the amount of water that flows into the cistern. Every man gets, in the measure in which he desires. Though a tremulous hand may hold out a cup into which Jesus Christ will not refuse to pour the wine of the kingdom, yet the tremulous hand will spill much of the blessing; and he that would have the full enjoyment of the mercies promised, and possible, must 'ask in faith, nothing wavering.' The sensitive paper which records the hours of sunshine in a day has great gaps upon its line of light answering to the times when clouds have obscured the sun; and the communication of blessings from God is intermittent, if there be intermittency of faith. If you desire an unbroken line of mercy, joy, and peace, keep up an unbroken continuity of trustful confidence.
IV. Lastly, we have here the education of faith.
Christ paid no heed in words to the man's confession of unbelief, but proceeded to do the work which answered his prayer in both its possible meanings. He responded to imperfect confidence by His perfect work of cure, and, by that perfect work of cure, He strengthened the imperfect confidence which it had answered.
Thus He educates us by His answers--His over-answers--to our poor desires; and the abundance of His gifts rebukes the poverty of our petitions more emphatically than any words of remonstrance beforehand could have done. He does not lecture us into faith, but He blesses us into it. When the Apostle was sinking in the flood, Jesus Christ said no word of reproach until He had grasped him with His strong hand and held him safe. And then, when the sustaining touch thrilled through all the frame, then, and not till then, He said--as we may fancy, with a smile on His face that the moonlight showed--as knowing how unanswerable His question was, 'O thou of little faith, _wherefore_ didst thou doubt?' That is how He will deal with us if we will; over-answering our tremulous petitions, and so teaching us to hope more abundantly that 'we shall praise Him more and more.'
