2 Samuel 7:28-29

2 Samuel 7:28-29. And now, O Lord GOD, thou art that God, and thy words be true, and thou hast promised this goodness unto thy servant: Therefore now let it please thee to bless the house of thy servant, that it may continue for ever before thee: for thou, O Lord GOD, hast spoken it:

There is that grand pleading again: "Thou, O Lord God, hast spoken it." If you can remind God of his own promise, you may have whatsoever you will of him; if he has said anything, his word shall surely be fulfilled.
