"Do as thou hast said, that thy name may be magnified forever" (1 Chron. 17:23-24).
This is a most blessed phase of true prayer. Many a time we ask for things which are not absolutely promised. We are not sure therefore until we have persevered for some time whether our petitions are in the line of God's purpose or no. There are other occasions, and in the life of David this was one, when we are fully persuaded that what we ask is according to God's will. We feel led to take up and plead some promise from the page of Scripture, under the special impression that it contains a message for us. At such times, in confident faith, we say, "Do as Thou hast said." There is hardly any position more utterly beautiful, strong, or safe, than to put the finger upon some promise of the Divine word, and claim it. There need be no anguish, or struggle, or wrestling; we simply present the check and ask for cash, produce the promise, and claim its fulfillment; nor can there be any doubt as to the issue. It would give much interest to prayer, if we were more definite. It is far better to claim a few things specifically than a score vaguely. --F. B. Meyer
Every promise of Scripture is a writing of God, which may be pleaded before Him with this reasonable request: "Do as Thou hast said." The Creator will not cheat His creature who depends upon His truth; and far more, the Heavenly Father will not break His word to His own child.
"Remember the word unto thy servant, on which thou hast caused me to hope," is most prevalent pleading. It is a double argument: it is Thy Word. Wilt Thou not keep it? Why hast thou spoken of it, if Thou wilt not make it good. Thou hast caused me to hope in it, wilt Thou disappoint the hope which Thou has Thyself begotten in me? --C. H. Spurgeon
"Being absolutely certain that whatever promise he is bound by, he is able also to make good" (Rom. 4:21, Weymouth's Translation).
It is the everlasting faithfulness of God that makes a Bible promise "exceeding great and precious." Human promises are often worthless. Many a broken promise has left a broken heart. But since the world was made, God has never broken a single promise made to one of His trusting children.
Oh, it is sad for a poor Christian to stand at the door of the promise, in the dark night of affliction, afraid to draw the latch, whereas he should then come boldly for shelter as a child into his father's house. --Gurnal
Every promise is built upon four pillars: God's justice and holiness, which will not suffer Him to deceive; His grace or goodness, which will not suffer Him to forget; His truth, which will not suffer Him to change, which makes Him able to accomplish. --Selected
