6:7 But when ye pray, use not {c} vain repetitions, as the heathen [do]: for they think that they shall be heard for their much speaking.
(c) Long prayers are not condemned, but vain, needless, and superstitious ones.
6:7 Use not vain repetitions, as the heathen [do]. What is forbidden is not much praying, nor praying in the same words (the Lord did both), but making the number of prayers, length of prayers, or time spent in praying, a point of observance and of merit. 1Ki 18:26 gives an example of the repetitions of the heathen. Mohammedans and Catholics still hold that there is merit in repeating certain prayers a set number of times.
6:7 Use not vain repetitions - To repeat any words without meaning them, is certainly a vain repetition. Therefore we should be extremely careful in all our prayers to mean what we say; and to say only what we mean from the bottom of our hearts. The vain and heathenish repetitions which we are here warned against, are most dangerous, and yet very common; which is a principal cause why so many, who still profess religion, are a disgrace to it. Indeed all the words in the world are not equivalent to one holy desire. And the very best prayers are but vain repetitions, if they are not the language of the heart.
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.
