The Power of Faith
Matthew 17:20
And Jesus said to them, Because of your unbelief: for truly I say to you, If you have faith as a grain of mustard seed…


This was the comment of our Lord on the failure of the disciples to cure the lunatic boy, and on his own subsequent success. The difference was accounted for by the fact that the disciples had not faith, while Christ possessed it. On another occasion, when there was no question of any attempt of his disciples, our Lord answered the amazement caused by one of his miracles by pointing in a similar way to the power of faith (Matthew 21:21).

I. THE FAITH.

1. Its existence. "If ye have faith." These words imply uncertainty. Many people have much religion, but no faith. They have a creed, but not faith. They do not really and actively trust God. Faith begins in us when we put our belief into action.

2. Its smallness. It may be but as a grain of mustard seed. It is sad to think of its being so minute; certainly there is no virtue in its meagreness. Yet even a small faith may do great things if it is indeed a real faith. The great question is not - How many things do we believe? but - How firm is our grasp upon the objects of faith? The area of belief may be vast as a windswept desert, and faith may be small as a shepherd's cot. Then it is that little hut of faith that saves us, while the storm passes overhead.

3. Its life. The mustard seed is better than a grain of sand. It is alive, and therefore it can grow. The living faith will not be always small. But even while it is small it is capable of wonderful. possibilities.

II. THE WORK OF FAITH.

1. An active work. Christ here speaks of what faith does, and the author of the Epistle to the Hebrews recites achievements of faith (Hebrews 11.). Faith not only affords shelter in trouble, it is an inspiration for service. The man of faith is the man of action, for he has within him a fountain of energy. It is, therefore, an utter mistake to suppose that "believing" is to be instead of "doing." Faith is given to enable us to do great things which we could not accomplish without it.

2. A great work. This small faith is to accomplish grand results. The mustard seed is to remove a mountain. Only a foolish literalism can occasion any perplexity in the reading of Christ's words. His disciples were too familiar with Oriental metaphors to fall into the absurd mistake of supposing that Jesus really expected them to toss mountains of rock and earth from one place to another. It was customary for the Jews to refer to a great rabbi as a remover of mountains, and therefore Christ was employing proverbial language which would be well understood by his hearers. But this does not mean that his words contained no statement of importance. What it teaches is that faith can accomplish stupendous achievements, such as the strongest men' would fail in attempting without it.

3. A work of removing difficulties. The forerunner of Christ was to lower mountains in order to prepare the way for the King (Isaiah 40:4). There are many hindrances in the path of Christian work. Some of these seem to be insuperable. Sultans frown on the gospel; empires bar their gates against it. But faith, working by prayer, has removed many such a mountain of difficulty, and it will do so again. - W.F.A.
