Charles H. Spurgeon on Psalms 86:5

Ready to forgive. The mercy of God is a ready mercy, and his pardons are ready for his people; his pardons and mercies are not to seek, he hath them at hand, he is good and ready to forgive. Whereas most men, though they will forgive, yet they are not ready to forgive, they are hardly brought to it, though they do it at last. But God is "ready to forgive"; he hath, as it were, pardons ready drawn (as a man who would be ready to do a business, he will have such writings as concern the passing of it ready); there is nothing to do but to put in the date and the name; yea indeed, the date and the name are put in from all eternity. Thus the Scripture speaks to show how forward God is to do good; he needs not set his heart to it; his heart is ever in the exactest fitness. —Joseph Caryl.
