No man can know the greatness of sin till he has felt it, for there is no measuring-rod for sin, except its condemnation in our own conscience, when the law of God speaks to us with a terror that may be felt. Some men imagine that the Gospel was devised, in some way or other, to soften down the harshness of God towards sin. Ah! how mistaken the idea! There is no more harsh condemnation of sin anywhere than in the Gospel.
