Quite a sufficient guide as to how God should be addressed is afforded by the Lord's Prayer. It was given by the Master in response to the earnest request of His disciples for instruction in prayer. Brief, compact and complete, it is as it were the Christian seed-prayer. Once let it be planted in the heart of a Church or the soul of a child of God and it will grow into the glowing devotion of wondrous collects and rich liturgies. Indeed there is no Christian prayer worth anything which does not owe its whole merit to the Lord's Prayer; and the noblest liturgy of the Church is but the expansion and application of the same. Hence it is the touchstone of all prayer. By it the Christian's mode of address to God is finally approved or condemned. How important is it, then, that a man should know the Lord's Prayer!--know it, not merely as a formula, but as the embodiment of the vital principles of converse with God. The process of yore must be repeated by the disciples of to-day. Like their predecessors of Galilee they must approach the unchangeable One and prefer the old entreaty: "Lord, teach us to pray." Nothing short of this will suffice. Then if they listen they will receive the familiar measures of the "Our Father" as a new and personal gift fresh and living from the lips of Jesus. It is good sometimes to "wait still upon God" between the sentences, and let the Holy Spirit apply each several petition to one's own special case and to all those interests which concern one's life--in sooth, translate it into the terms of our own day and generation. It is thus that the compressed richness of the Lord's Prayer is unfolded. The Lord's Prayer is one of those most precious of things known as common property. But a common possession to be worth anything to anybody must be related by every one of the multitude who claim a share in it, each to his own personality. Before common property can fully justify its claim to be common, it must become in a sense private by a process of implicit appropriation on the part of the individuals concerned. So while the Lord's Prayer ideally belongs to every child of God as the common heritage of prayer, it actually belongs only to those who have recognized and used it as a personal, though not exclusive, gift from its Author.
