Underneath all the arches of Scripture history, throughout the whole grand temple of the Scriptures, these two voices ever echo, man is ruined, man is redeemed.
Christ is redemption only as He actually redeems and delivers our nature from sin. If He is not the law and spring of a new spirit of life, He is nothing. "As many as are led by the Spirit of God, they are the sons of God,"—as many, no more.
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.
Whatever in Christ had the nature of satisfaction, was by virtue of His suffering or humiliation; whatever had the nature of merit, was by virtue of His obedience or righteousness.
As God carries on the work of converting the souls of fallen men through all ages, so He goes on to justify them, to blot out all their sins, and to accept them as righteous in His sight through the righteousness of Christ. He goes on to adopt and receive them from being the children of Satan to be His own children, to carry on the work of His grace which He has begun in them, to comfort them with the consolations of His Spirit, and to bestow upon them, when their bodies die, that eternal glory which is the fruit of Christ's purchase.
