There is a danger to be carefully guarded against in the reading of this book and in the consideration of the precious truth. The incidents it relates bring before the mind, of the unlimited resources and the unquenchable love of God, that are made available to believing prayer. That danger has been suggested by what has been said, that the highest use of prayer is to bring the soul nearer to God, and _not the making of it a mere matter of convenience to escape physical ills or supply physical necessities_. "That which is born of the flesh is flesh" and continues flesh until the end. "Have no confidence in the flesh" is always a much needed exhortation. Now, unquestionably, the desires of the natural heart may and do deceive us, and often lead as to believe that our fervent earnest prayer for temporal blessing is led of the Spirit, when the mind of the Spirit is, that we will be made more humble, more Christ-like and more useful by being denied than by being granted. Again, we are in danger of disobeying the plain commands of _God's word_ in allowing prayer ever to take the place of anything _in our power_ to do, and _that we are commanded to do as a means to secure needed good_. He who has said "pray always," has also said, "Be ambitious to be quiet and to do your own business, and to work with your hands, even as we charged you; that ye may walk honestly toward them that are without, and may have need of nothing." (1 Thess., iv., 11, 12; R.V.) How often the _flesh_ has led men to read (Phil, iv., 19): "My God shall supply all your need according to his riches in glory by Christ Jesus," in a spirit entirely opposed to this exhortation. They have ceased to labor with their hands, and, without warrant in the providences of God and the judgment of brethren, have turned from doing their own business, expecting the Lord to pay their debts and provide for their necessities. The quotations of Scripture made by our Lord to Satan, "Thou shalt not tempt the Lord, thy God," is surely applicable in all such cases. The spirit of a "sound mind" (see 2 Tim. i., 7) will surely recognize this. So in _all_ things, that which God has given me intelligence and power to do, in avoiding evil or securing good, I am under direct command from him to do, always depending upon His blessing to secure the needed result. A _true faith_ in God will be made manifest by careful obedience to known commands. An _intelligent_ faith can never allow dependence upon means used to take the place of dependence upon the living God, who alone makes them efficacious.
