Charles H. Spurgeon on Psalms 77:8

Is his mercy clean gone for ever? If he has no love for his elect, has he not still his mercy left? Has that dried up? Has he no pity for the sorrowful? Doth his promise fail for evermore? His word is pledged to those who plead with him; is that become of none effect? Shall it be said that from one generation to another the Lord's word has fallen to the ground; whereas aforetime he kept his covenant to all generations of them that fear him? It is a wise thing thus to put unbelief through the catechism. Each one of the questions is a dart aimed at the very heart of despair. Thus have we also in our days of darkness done battle for life itself.
