Psalm 136:4—“To him who alone doeth great wonders: for his mercy endureth for ever.”

Psalm 136 is a magnificent hymn of thanksgiving, “Great Hallel”,  in which every declaration of God's mighty works is followed by the refrain, “for his mercy endureth for ever”. Verse 4 stands as the majestic transition between the introductory praises of God's character and the chronological retellings of creation and deliverance. 

In verse 4, the psalmist exalts the Lord as the One “who alone doeth great wonders”. The emphasis on “alone” declares God's absolute uniqueness. No created being, no idol, and no earthly power can accomplish the marvellous works that belong exclusively to the sovereign Creator.

The “great wonders” encompass God's works of creation, providence, redemption, and continual preservation of His people. From creating the heavens (vv. 5–9), delivering Israel from Egypt (vv. 10–15), guiding them through the wilderness (v. 16), and providing for all flesh (v. 25), every mighty act reveals His infinite wisdom and omnipotent power. Yet the psalm repeatedly teaches that behind every wonder stands God's enduring covenant mercy. 

God's wonders are never mere displays of power. His mighty hand is always directed by His steadfast love toward His people. When we face circumstances beyond our ability, let us remember that the God who alone performs great wonders remains unchanged. His power has not diminished, nor has His mercy failed. Therefore, trust Him, praise Him, and rest confidently in His unfailing love, “for his mercy endureth for ever”. The greatest wonder of all is His redeeming love in Jesus Christ, through whom sinners receive forgiveness, eternal life, and reconciliation with God (Ephesians 2:4–7).
