4 Will evildoers never understand? They eat up my people like they eat up bread; they do not call on Yahveh. 5 Then they will be filled with fright because God is with those who are righteous. 6 You sinners frustrate the plans of the oppressed, but Yahveh is his refuge. 7 Oh, that Israel’s deliverance would come from Zion! When Yahveh restores the well-being of his people, let Jacob rejoice, let Israel be glad.
The psalmist calls on a people whose plans are being frustrated, and whose well-being has been lost. That I can understand. I know what it feels like to be wronged. Faith calls me to rejoice and be glad. I don’t feel like doing that. But if I truly believe in God, I will worship and praise him for my coming deliverance.
