“By Christ's purchasing redemption, two things are intended, His satisfaction, and His merit. All is done by the price that Christ lays down, which does two things: it pays our debt, and so it satisfies; by its intrinsic value, and by the agreement between the Father and the Son it procures our title, and so it merits. The satisfaction of Christ is to free us from misery, and the merit of Christ is to purchase happiness for us.”
