The toil of prayer shows us the work involved in it. Sometimes we hear the expression, "If you can do nothing else, you can pray," as though prayer were the easiest of all things. As a simple fact, it is the hardest. No man knows what prayer means unless he knows what it is to "labour" in prayer. The strife involved in prayer implies opposition--the opposing force of one who wishes above all things to check and thwart our prayers. We discern something of this opposition in the well-known words, "We wrestle" (Eph. vi. 12); and the words of the hymn are as true as they are familiar-- "And Satan trembles when he sees The weakest saint upon his knees." The Apostle knew by spiritual experience that to pray was to rouse up against himself a mighty opposition, and it was this force that made his prayer such a "great conflict." No believer should be surprised at his prayers "being hindered" (1 Pet. iii. 7). It is evidently one of Satan's main objects to get the Christian to restrain prayer. The Christian man or the Christian Church that continues instant in prayer may rest assured of malignant opposition from the hosts of spiritual wickedness in high places. On the other hand, we may be sure that Satan scarcely troubles himself about the believer or congregation whose private, family, and public praying is neglected or thought little of. Prayer is, therefore, a "great conflict." It is not solicitude only, but a struggle; not merely anxiety, but activity. As Bishop Moule says: "Prayer is never meant to be _indolently_ easy, however simple and reliant it may be. It is meant to be an infinitely important transaction between man and God. And therefore very often, when subjects and circumstances call for it, it has to be viewed as a work involving labour, persistency, conflict, if it would be prayer indeed" (_Colossian Studies_, p. 124). The Bishop goes on to quote a familiar incident which illustrates this great truth: "A visitor knocked betimes one morning at the door of a good man, a saint of the noblest Puritan type--and that was a fine type indeed. He called as a friend to consult a friend, sure of his welcome. But he was kept waiting long. At last a servant came to explain the delay: 'My master has been at prayer, and this morning he has been long in getting access.'" The practical question for us is whether this is our idea of prayer, or whether we are merely playing at prayer, and not regarding it with true seriousness. If we know what it is to have "great conflict" in prayer, happy are we. If we do not, we may well ask God to search our hearts and change our minds about prayer.
