Commentaries
6:5-8 It is taken for granted that all who are disciples of Christ pray. You may as soon find a living man that does not breathe, as a living Christian that does not pray. If prayerless, then graceless. The Scribes and Pharisees were guilty of two great faults in prayer, vain-glory and vain repetitions. Verily they have their reward; if in so great a matter as is between us and God, when we are at prayer, we can look to so poor a thing as the praise of men, it is just that it should be all our reward. Yet there is not a secret, sudden breathing after God, but he observes it. It is called a reward, but it is of grace, not of debt; what merit can there be in begging? If he does not give his people what they ask, it is because he knows they do not need it, and that it is not for their good. So far is God from being wrought upon by the length or words of our prayers, that the most powerful intercessions are those which are made with groanings that cannot be uttered. Let us well study what is shown of the frame of mind in which our prayers should be offered, and learn daily from Christ how to pray.
6. But thou, when thou prayest, enter into thy closet—a place of retirement.
and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly—Of course, it is not the simple publicity of prayer which is here condemned. It may be offered in any circumstances, however open, if not prompted by the spirit of ostentation, but dictated by the great ends of prayer itself. It is the retiring character of true prayer which is here taught.
