6 But when you pray, go away by yourself, shut the door behind you, and pray to your Father in private. Then your Father, who sees everything, will reward you. 7 "When you pray, don't babble on and on as people of other religions do. They think their prayers are answered merely by repeating their words again and again.
Matthew Henry's Commentary on Matthew 6:6-7
Commentary on Matthew 6:5-8
(Read Matthew 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.
