Psalm 79
This is a psalm of Asaph, it seems to have been written after the Babylonian invasion, when many died, and the temple was ruined. The psalmist calls out to God, telling Him of the destruction, he knows that it is ultimately the result of God’s anger against them and calls out for God to judge the nations. For in attacking God’s people the nations are attacking God. The psalmist knows that it is the sins of past generations that are the real cause, so he calls on God to have mercy on them, for Him to deliver them and to forgive their sins. Recognising our sins and looking for mercy and forgiveness are the only way to properly approach God. This will bring glory to God. God’s name is glorified when people repent and are restored by His grace.
