Charles Spurgeon Commentary Matthew 9:29

"Then touched he their eyes, saying, According to your faith be it done unto you." — Matthew 9:29 (ASV)

Then touched he their eyes, saying, according to your faith be it unto you.

Again he arouses their faith; and this time he throws the whole responsibility upon their confidence in him. According to your faith be it unto you. He touched them with his hand; but they must also touch him with their faith.

The word of power in the last sentence is one upon which he acts so continually, that we may call it, regarding many blessings, a rule of the kingdom. We have the measuring of our own mercies; our faith obtains less or more according to its own capacity to receive.

Had these men been mere pretenders to faith, they would have remained blind. If we will not truly trust our Lord, we shall die in our sins.
