Behold, I was shapen in iniquity; and in sin did my mother conceive me.—PSALM 51:5.
The end of the ministry of the gospel is to bring sinners unto Christ. Their way to this end lies through the sense of their misery without Christ. The ingredients of this misery, are our sinfulness, original and actual; the wrath of God, whereto sin has exposed us; and our impotency to free ourselves either from sin or wrath. That we may therefore promote this great end, we shall endeavour, as the Lord will assist, to lead you in this way, by the sense of misery, to him who alone can deliver from it. Now the original of our misery being the corruption of our natures, or original sin, we thought fit to begin here, and therefore have pitched upon these words as very proper for our purpose.
