11:19-26 The disciples could not think why that fig-tree should so soon wither away; but all wither who reject Christ; it represented the state of the Jewish church. We should rest in no religion that does not make us fruitful in good works. Christ taught them from hence to pray in faith. It may be applied to that mighty faith with which all true Christians are endued, and which does wonders in spiritual things. It justifies us, and so removes mountains of guilt, never to rise up in judgment against us. It purifies the heart, and so removes mountains of corruption, and makes them plain before the grace of God. One great errand to the throne of grace is to pray for the pardon of our sins; and care about this ought to be our daily concern.

23. For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed … he shall have whatsoever he saith—Here is the lesson now. From the nature of the case supposed—that they might wish a mountain removed and cast into the sea, a thing far removed from anything which they could be thought actually to desire—it is plain that not physical but moral obstacles to the progress of His kingdom were in the Redeemer's view, and that what He designed to teach was the great lesson, that no obstacle should be able to stand before a confiding faith in God.
