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.

25. And when ye stand praying, forgive, if ye have aught against any; that your Father also which is in heaven may forgive you your trespasses, &c.—This is repeated from the Sermon on the Mount (see on [1479]Mt 6:12); to remind them that if this was necessary to the acceptableness of all prayer, much more when great things were to be asked and confidently expected.
