C.H. Spurgeon: Justification by grace is irreconcilably antithetical to justification by works

C.H. Spurgeon asserts that justification by works is more appealing to natural man than justification by grace; at root, this is because of man's humanism: he wants to become God's creditor so that God becomes his slave and he becomes God's god --

If I could preach justification to be bought by you at a sovereign a piece, who would go out of the place without being justified? If I could preach justification to you by walking a hundred miles, would we not be pilgrims tomorrow morning, every one of us? If I were to preach justification which would consist in whippings and torture, there are very few here who would not whip themselves, and that severely too. But when it is freely, freely, freely, men turn away. "What! am I to have it for nothing at all, without doing anything?" Yes, Sir, you are to have it for nothing, or else not at all; it is "freely." "But may I not go to Christ, lay some claim to his mercy, and say, Lord, justify me because I am not so bad as others?" It will not do, Sir, because it is "by his grace." "But may I not indulge a hope, because I go to church twice a day?" No, Sir; it is "by his grace." "But may I not offer this plea, I mean to be better?" No, sir; it is "by his grace." You insult God by bringing your counterfeit coin to pay for his treasures. Oh! what poor ideas men have of the value of Christ's gospel, if they think they can buy it! God will not have your rusty farthings to buy heaven with. A rich man once, when he was dying, had a notion that he could buy a place in heaven by building a row of almshouses. A good man stood by his bed-side, and said, "How much more are you going to leave?" "Twenty thousand pounds." Said he "That would not buy enough for your foot to stand on in heaven; for the streets are made of gold there, and therefore of what value can your gold be, it would be accounted nothing of, when the very streets are paved with it?" Nay, friends, we cannot buy heaven with gold nor good works, nor prayers, nor anything in the world. But how is it to be got? Why it is to be got for asking only. As many of us as know ourselves to be sinners may have Christ for asking for him. Do you know that you want Christ? You may have Christ! "Whosoever will, let him come and take of the water of life freely." But if you cleave to your own notions, and say, "No, Sir, I mean to do a great many good things, and then I will believe in Christ."—Sir, you will be damned if you hold by such delusions. I earnestly warn you. You cannot be saved so. "Well, but are we not to do good works?" Certainly you are; but you are not to trust in them. You must trust in Christ wholly, and then do good works afterwards. "But," says one, "I think if I were to do a few good works, it would be a little recommendation when I came." It would not, sir; they would be no recommendation at all. Let a beggar come to your house in white kid gloves, and say he is very badly off, and wants some charity; would the white kid gloves recommend him to your charity? Would a good new hat that he has been buying this morning recommend him to your charity? "No," you would say, "you are a miserable impostor; you do not want anything, and you shall not have anything either! Out with you!" (C.H. Spurgeon, Justification by Grace)
