“Jesus Christ came into the world to save sinners. It is a very surprising thing—a thing to be marveled at most of all by those who enjoy it. I know that it is to me even to this day the greatest wonder that I ever heard of, that God should ever justify me. I feel myself to be a lump of unworthiness, a mass of corruption, and a heap of sin, apart from his almighty love. I know by a full assurance that I am justified by faith which is in Christ Jesus (Gal. 2:16), and treated as if I had been perfectly just, and made an heir of God and a joint heir with Christ (Gal. 4:7); and yet by nature I must take my place among the most sinful. I, who am altogether undeserving, am treated as if I had been deserving. I am loved with as much love as if I had always been godly, whereas aforetime I was ungodly. Who can help being astonished at this? Gratitude for such favor stands dressed in robes of wonder.
Now, while this is very surprising, I want you to notice how available it makes the gospel to you and to me. If God justifieth the ungodly, then, dear friend, he can justify you.”
– Charles Spurgeon, All of Grace, p.9-10
