Charles H. Spurgeon on Psalms 130:4

But there is forgiveness with thee, etc. His judgments and his wrath may make us astonished and stupefied; but, if there be no more they will never make us to come to God. Then if this be not sufficient, what more is requisite? Even a sight of the Lord's mercy, for that is most forcible to allure, as the prophet saith here, and as the church of God says (So 1:3), "Because of the savour of thy good ointments, therefore the virgins love thee." This only is forcible to allure the sinner: for all the judgments of God, and curses of the law, will never allure him. What was the chief thing that moved the prodigal son to return home to his father? Was it chiefly the distress, the disgrace and poverty where with he was burdened, or the famine that almost caused him to starve? No, but the chief thing was this, he remembered that he had a loving father. That maketh him to resolve with an humble confession to go home Lu 15:1-32 Even so is it with the sinner; it is not terrors and threatenings that chiefly will move him to come to God, but the consideration of his manifold and great mercies. —Robert Rollock.
