“Et inde profecti prætergrediebantur Galilæam : nec volebat quemquam scire.”
“And he said unto them, This kind can come forth by nothing, but by prayer and fasting.”
“Jesus answered, “This kind cannot come out, except by prayer.””
“He said to them, “This kind can come out by nothing, except by prayer and fasting.””

Verses 14-29 The father of the suffering youth reflected on the want of power in the disciples; but Christ will have him reckon the disappointment to the want of faith. Very much is promised to our believing.

Those that complain of unbelief, must look up to Christ for grace to help them against it, and his grace will be sufficient for them. Whom Christ cures, he cures effectually. But Satan is unwilling to be driven from those that have been long his slaves, and, when he cannot deceive or destroy the sinner, he will cause him all the terror that he can. The disciples must not think to do their work always with the same ease; some services call for more than ordinary pains.
