You are the God who works wonders; You display Your strength among the peoples.
PSALM 77 Whoever was the penman of this psalm, the Holy Spirit seems, by his mouth, to have dictated a common form of prayer for the Church in her afflictions, that even under the most cruel persecutions the faithful might not fail to address their prayers to heaven.
Commenting on Psalm 77:1-20
Thou art the God that doest wonders. Thou alone art Almighty. The false gods are surrounded with the pretence of wonders, but you really work them. It is thy peculiar prerogative to work marvels; it is no new or strange thing with thee, it is according to thy wont and use. Herein is renewed reason for holy confidence.
The psalmist here recovers himself out of the great distress and plague he was in, and silences his own fears of God's casting off his people by the remembrance of the great things he had done for them formerly, which though he had in vain tried to quiet himself with (Psa 77:5, Psa 77:6) yet he tried again, and, upon this second trial, found it not in vain.
