Charles H. Spurgeon on Psalms 74:21

O let not the oppressed return ashamed. Though broken and crushed they come to thee with confidence; suffer them not to be disappointed, for then they will be ashamed of their hope. Let the poor and needy praise thy name. By thy speedy answer to their cries make their hearts glad, and they will render to thee their gladdest songs. It is not the way of the Lord to allow any of those who trust in him to be put to shame; for his word is, "He shall call upon me, and I will deliver him, and he shall glorify me."
