The space occupied by prayer in the Sermon on the Mount bespeaks its estimate by Christ and the importance it holds in His system. Many important principles are discussed in a verse or two. The Sermon consists of one hundred and eleven verses, and eighteen are about prayer directly, and others indirectly. Prayer was one of the cardinal principles of piety in every dispensation and to every child of God. It did not pertain to the business of Christ to originate duties, but to recover, to recast, to spiritualise, and to re-enforce those duties which are cardinal and original. With Moses the great features of prayer are prominent. He never beats the air nor fights a sham battle. The most serious and strenuous business of his serious and strenuous life was prayer. He is much at it with the intensest earnestness of his soul. Intimate as he was with God, his intimacy did not abate the necessity of prayer. This intimacy only brought clearer insight into the nature and necessity of prayer, and led him to see the greater obligations to pray, and to discover the larger results of praying. In reviewing one of the crises through which Israel passed, when the very existence of the nation was imperilled, he writes: “I fell down before the Lord forty days and forty nights.” Wonderful praying and wonderful results! Moses knew how to do wonderful praying, and God knew how to give wonderful results. The whole force of Bible statement is to increase our faith in the doctrine that prayer affects God, secures favors from God, which can be secured in no other way, and which will not be bestowed by God if we do not pray. The whole canon of Bible teaching is to illustrate the great truth that God hears and answers prayer. One of the great purposes of God in His book is to impress upon us indelibly the great importance, the priceless value, and the absolute necessity of asking God for the things which we need for time and eternity. He urges us by every consideration, and presses and warns us by every interest. He points us to His own Son, turned over to us for our good, as His pledge that prayer will be answered, teaching us that God is our Father, able to do all things for us and to give all things to us, much more than earthly parents are able or willing to do for their children. Let us thoroughly understand ourselves and understand, also, this great business of prayer. Our one great business is prayer, and we will never do it well without we fasten to it by all binding force. We will never do it well without arranging the best conditions of doing it well. Satan has suffered so much by good praying that all his wily, shrewd and ensnaring devices will be used to cripple its performances. We must, by all the fastenings we can find, cable ourselves to prayer. To be loose in time and place is to open the door to Satan. To be exact, prompt, unswerving, and careful in even the little things, is to buttress ourselves against the Evil One.
