Matthew Henry on Psalms 130:5-8

It is for the Lord that my soul waits, for the gifts of his grace, and the working of his power. We must hope for that only which he has promised in his word. Like those who wish to see the dawn, being very desirous that light would come long before day; but still more earnestly does a good man long for the tokens of God's favour, and the visits of his grace. Let all that devote themselves to the Lord, cheerfully stay themselves on him. This redemption is redemption from all sin. Jesus Christ saves his people from their sins, both from the condemning and from the commanding power of sin. It is plenteous redemption; there is an all-sufficient fulness in the Redeemer, enough for all, enough for each; therefore enough for me, says the believer. Redemption from sin includes redemption from all other evils, therefore it is a plenteous redemption, through the atoning blood of Jesus, who shall redeem his people from all their sins. All that wait on God for mercy and grace, are sure to have peace.
