8 Is his mercy clean gone for ever? doth his promise fail for evermore 
8 Has his unfailing love vanished forever? Has his promise failed for all time?
8 Has his steadfast love forever ceased? Are his promises at an end for all time?
8 Is his love worn threadbare? Has his salvation promise burned out?
8 Has His mercy ceased forever? Has His promise failed forevermore?
8 Is his unfailing love gone forever? Have his promises permanently failed?
Matthew Henry's Commentary on Psalm 77:8
Commentary on Psalm 77:1-10
(Read Psalm 77:1-10)
Days of trouble must be days of prayer; when God seems to have withdrawn from us, we must seek him till we find him. In the day of his trouble the psalmist did not seek for the diversion of business or amusement, but he sought God, and his favor and grace. Those that are under trouble of mind, must pray it away. He pored upon the trouble; the methods that should have relieved him did but increase his grief. When he remembered God, it was only the Divine justice and wrath. His spirit was overwhelmed, and sank under the load. But let not the remembrance of the comforts we have lost, make us unthankful for those that are left. Particularly he called to remembrance the comforts with which he supported himself in former sorrows. Here is the language of a sorrowful, deserted soul, walking in darkness; a common case even among those that fear the Lord, Isaiah 50:10. Nothing wounds and pierces like the thought of God's being angry. God's own people, in a cloudy and dark day, may be tempted to make wrong conclusions about their spiritual state, and that of God's kingdom in the world. But we must not give way to such fears. Let faith answer them from the Scripture. The troubled fountain will work itself clear again; and the recollection of former times of joyful experience often raises a hope, tending to relief. Doubts and fears proceed from the want and weakness of faith. Despondency and distrust under affliction, are too often the infirmities of believers, and, as such, are to be thought upon by us with sorrow and shame. When, unbelief is working in us, we must thus suppress its risings.
