Although my house be not so with God; yet he hath made with me an everlasting covenant, ordered in all things, and sure: for this is all my salvation, and all my desire, although he make it not to grow. 2 Samuel 23:5
This is not so much one promise as an aggregate of promises—a box of pearls. the covenant is the ark which contains all things. These are the last words of David, but they may be mine today. Here is a sigh: things are not with me and mine as I could wish; there are trials, cares, and sins. These make the pillow hard. Here is a solace—"He hath made with me an everlasting covenant." Jehovah has pledged Himself to me, and sealed the compact with the blood of Jesus. I am bound to my God and my God to me. This brings into prominence a security, since this covenant is everlasting, well ordered, and sure. There is nothing to fear from the lapse of time, the failure of some forgotten point, or the natural uncertainty of things. The covenant is a rocky foundation to build on for life or for death. David feels satisfaction: he wants no more for salvation or delectation. He is delivered, and he is delighted. The covenant is all a man can desire. O my soul, turn thou this day to thy Lord Jesus, whom the great Lord has given to be a covenant to the people. Take Him to be thine all in all.
