Matthäus 6:15

But if ye forgive not, &c.--See on Mat 6:12. Fasting (Mat 6:16-18). Having concluded His supplementary directions on the subject of prayer with this Divine Pattern, our Lord now returns to the subject of Unostentatiousness in our deeds of righteousness, in order to give one more illustration of it, in the matter of fasting.

Christ having, in the former chapter, armed his disciples against the corrupt doctrines and opinions of the scribes and Pharisees, especially in their expositions of the law (that was called their leaven, Mat 16:12), comes in this chapter to warn them against their corrupt practices, against the two sins which, though in their doctrine they did not justify, yet in their conversation they were notoriously guilty of, and so as even to recommend them to their admirers: these were hypocrisy and worldly-mindedness, sins which, of all others, the professors of religion need most to guard against, as sins that most easily beset those who have escaped the grosser pollutions that are in the world through lust, and which are therefore highly dangerous. We are here cautioned, I. Against hypocrisy; we must not be as the hypocrites are, nor do as the hypocrites do. 1. In the giving of alms (Mat 6:1-4). 2. In prayer (Mat 6:5-8). We are here taught what to pray for, and how to pray (Mat 6:9-13); and to forgive in prayer (Mat 6:14, Mat 6:15). 3. In fasting (Mat 6:16-18). II. Against worldly-mindedness, 1. In our choice, which is the destroying sin of hypocrites (Mat 6:19-24). 2. In our cares, which is the disquieting sin of many good Christians (Mat 6:25-34).
