There follows from that thought this practical lesson, that the discovery of much unbelief should never make a man doubt the reality or genuineness of his little faith. We are all apt to write needlessly bitter things against ourselves when we get a glimpse of the incompleteness of our Christian life and character. But there is no reason why a man should fancy that he is a hypocrite because he finds out that he is not a perfect believer. But, on the other hand, let us remember that the main thing is not the maturity, but the progressive character, of faith. It was most natural that this man in our text, at the very first moment when he began to put his confidence in Jesus Christ as able to heal his child, should be aware of much tremulousness mingling with it. But is it not most unnatural that there should be the same relative proportion of faith and unbelief in the heart and experience of men who have long professed to be Christians? You do not expect the infant to have adult limbs, but you do expect it to grow. True, faith at its beginning may be like a grain of mustard seed, but if the grain of mustard seed be alive it will grow to a great tree, where all the fowls of the air can lodge in the branches. Oh! it is a crying shame and sin that in all Christian communities there should be so many grey-headed babies, men who have for years and years been professing to be Christ's followers, and whose faith is but little, if at all, stronger—nay! perhaps is even obviously weaker—than it was in the first days of their profession. 'Ye have need of milk, and not of strong meat,' very many of you. And the vitality of your faith is made suspicious, not because it is feeble, but because it is not growing stronger.

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.'

The disappointments, the weaknesses, the shameful defeats which come when our confidence fails, are another page of His lesson-book. The same Apostle of whom I have been speaking got that lesson when, standing on the billows, and, instead of looking at Christ, looking at their wrath and foam, his heart failed him, and because his heart failed him he began to sink. If we turn away from Jesus Christ, and interrupt the continuity of our faith by calculating the height of the breakers and the weight of the water that is in them, and what will become of us when they topple over with their white crests upon our heads, then gravity will begin to work, and we shall begin to sink. And well for us if, when we have sunk as far as our knees, we look back again to the Master and say, 'Lord, save me; I perish!' The weakness which is our own when faith sleeps, and the rejoicing power which is ours because it is His, when faith wakes, are God's education of it to fuller and ampler degrees and depth. We shall lose the meaning of life, and the best lesson that joy and sorrow, calm and storm, victory and defeat, can give us, unless all these make us 'rooted and grounded in faith.'

Dear friend, do you desire your truest good? Do you know that you cannot win it, or fight for it to gain it, or do anything to obtain it, in your own strength? Have you heard Jesus Christ saying to you, 'Come … and I will give you rest'? Oh! I beseech you, do not turn away from Him, but like this agonised father in our story, fall at His feet with 'Lord, I believe; help Thou mine unbelief,' and He will confirm your feeble faith by His rich response.
