If next we pass to Scripture teaching concerning prayer, where alone we find full instruction on the subject, in precept, example, and a variety of encouragements, it will appear that the warrant for prayer is found exclusively in the divine promise, and that the application of that promise is to every phase of life, subject to moral conditions which are explicitly revealed. Prayer is a privilege divinely bestowed through the Saviour, in accordance with which fellowship with God is granted on the merits of the Redeemer. Its nature reveals the true harmony between God and the moral creature, as a reality transcending all physical existence and all knowledge coming from study of physical law. The accepting of this privilege, and the continuance of its exercise are the tokens of returning harmony of sinful man with the holy God. Elevation in the exercise by steadily extending inclusion of a wider circle of personal desire and activity within the area of conscious fellowship with God, is the advance of the moral nature into fuller harmony with God, and with the whole government of the universe. The teaching of Scripture which assures of all this, and guides man towards realization of it, clearly distinguishes between material and moral good, yet does not exclude the one any more than the other, but subordinates the physical to the moral, harmonizing the two in recognition of the supreme importance of all that is moral. It does not exclude desire of temporal good, but restricts its illustration to desire of "daily bread,"--assures us that our Father knoweth we have need of such good, and will supply it,--and promises that having given most freely what is best, he will assuredly give that which is least.
