(21-22) And Peter calling to remembrance.--St. Mark alone names Peter as the speaker. The form of our Lord's answer, "Have faith in God," is also peculiar to him.

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.And Peter, calling to remembrance,.... Not so much the tree, and its spreading leaves, and the greatness of it, and the flourishing condition it was in, the other day, as the imprecation of Christ upon it:

saith unto him, Master, behold, the fig tree which thou cursedst is withered away; which he observed, as matter of astonishment, and as an instance of Christ's surprising power and authority; See Gill on Matthew 21:20.
