I daresay this opinion will startle some readers. I have little doubt that many look on eminent holiness as a kind of special gift, which none but a few must pretend to aim at. They admire it at a distance, in books: they think it beautiful when they see an example near themselves. But as to its being a thing within the reach of any but a very few, such a notion never seems to enter their minds. In short, they consider it a kind of monopoly granted to a few favoured believers, but certainly not to all. Now I believe that this is a most dangerous mistake. I believe that spiritual, as well as natural, greatness, depends far more on the use of means within everybody's reach, than on anything else. Of course I do not say we have a right to expect a miraculous grant of intellectual gifts. But this I do say, that when a man is once converted to God, whether he shall be eminently holy or not depends chiefly on his own diligence in the use of God's appointed means. And I assert confidently, that the principal means by which most believers have become great in the Church of Christ is the habit of _diligent private prayer_. Look through the lives of the brightest and best of God's servants, whether in the Bible or not. See what is written of Moses, and David, and Daniel, and Paul. Mark what is recorded of Luther and Bradford, the Reformers. Observe what is related of the private devotions of Whitfield, and Cecil, and Venn, and Bickersteth, and M'Cheyne. Tell me of one of all the goodly fellowship of saints and martyrs, who has not had this mark most prominently,--he was _a man of prayer_. Oh, depend upon it, prayer is power! Prayer obtains fresh and continued outpourings of the Spirit. He alone begins the work of grace in a man's heart: He alone can carry it forward and make it prosper. But the good Spirit loves to be entreated. And those who ask most, will always have most of His influence. Prayer is the surest remedy against the devil and besetting sins. That sin will never stand firm which is heartily prayed against: that devil will never long keep dominion over us which we beseech the Lord to cast forth. But, then, we must spread out all our case before our Heavenly Physician, if He is to give us daily relief: we must drag our indwelling devils to the feet of Christ, and cry to Him to send them back to the pit. Do we wish to grow in grace and be very holy Christians? Then let us never forget the value of prayer. VI. In the sixth place, _neglect of prayer is one great cause of backsliding_.
