More than ever, we live in a disposable culture. Think for a minute about some of the things that are made to be thrown away—razors, water bottles, lighters, paper plates, plastic eating utensils. Products are used, tossed, and then replaced.
This disposable culture is also reflected in more significant ways. Many times true commitment in relationships is seen as optional. Marriages struggle to survive. Long-term employees are discharged just before retirement for cheaper options. A highly revered athlete leaves to join another team. It seems as if nothing lasts.
Our unchanging God, however, has promised that His loving mercy endures forever. In Psalm 136, the singer celebrates this wonderful promise by making statements about God’s wonder, work, and character. He then punctuates each statement about God with the phrase, “For His mercy endures forever.” Whether it is the wonder of His creation (vv.4-9), the rescue of His people (vv.10-22), or His tender care for His own (vv.23-26), we can trust Him because His mercy will never fail. In a temporary world, the permanence of God’s mercy gives us hope. We can sing with the psalmist, “Oh, give thanks to the Lord, for He is good! For His mercy endures forever” (v.1).
Forever builded firm and sure,
Of faithfulness that never dies,
Established changeless in the skies. —Psalter
(2 Chron. 7:3,6), and by the armies of Jehoshaphat when they sang themselves into victory in the wilderness of Tekoa. From the striking form of it we should infer that it was a popular hymn among the Lord’s ancient people. Most hymns with a solid, simple chorus become favourites with congregations, and this is sure to have been one of the best beloved.” (Treasury of David)
