"I feel persuaded that false doctrine, inasmuch as it touches God's sovereignty, is always an object of divine jealousy. Let me indicate especially the doctrines of free-will. I know there are some good men who hold and preach them, but I am persuaded that the Lord must be grieved with their doctrine though he forgives them their sin of ignorance. Free-will doctrine—what does it? It magnifies man into God; it declares God's purposes a nullity, since they cannot be carried out unless men are willing. It makes God's will a waiting servant to the will of man, and the whole covenant of grace dependent upon human action. Denying election on the ground of injustice it holds God to be a debtor to sinners, so that if he gives grace to one he is bound to do so to all. It teaches that the blood of Christ was shed equally for all men and since some are lost, this doctrine ascribes the difference to man's own will, thus making the atonement itself a powerless thing until the will of man gives it efficacy. Those sentiments dilute the scriptural description of man's depravity, and by imputing strength to fallen humanity, rob the Spirit of the glory of his effectual grace: this theory says in effect that it is of him that willeth, and of him that runneth, and not of God that showeth mercy. Any doctrine, my brethren, which stands in opposition to this truth—"I will have mercy on whom I will have mercy," provokes God's jealousy. I often tremble in this pulpit lest I should utter anything which should oppose the sovereignty of my God; and though you know I am not ashamed to preach the responsibility of man to God—if God be a sovereign, man must be bound to obey him—on the other hand, I am equally bold to preach that God has a right to do what he wills with his own, that he giveth no account of his matters and none may stay his hand, or say unto him, "What doest thou?" I believe that the free-will heresy assails the sovereignty of God, and mars the glory of his dominion. In all faithfulness, mingled with sorrow, I persuade you who have been deluded by it, to see well to your ways and receive the truth which sets God on high, and lays the creature in the dust." —C. H. Spurgeon (1834-1892)
