But not as the offence, so also is the free gift. For if through the offence of one many be dead, much more the grace of God, and the gift by grace, which is by one man, Jesus Christ, hath abounded unto many. – Romans 5:15

All the benefits resulting from the Redeemer’s passion, and from all the works that followed upon it, are for those who by nature are ungodly. His gospel is that sinners believing in Him are saved. His sacrifice has put away sin from all who trust Him, and, therefore, it was offered for those who had sin upon them before. “He rose again for our justification,” but certainly not for the justification of those who can be justified by their own works. He ascended on high, and we are told that He “received gifts for men, yea, for the rebellious also.” He lives to intercede, and Isaiah tells us that “He made intercession for the transgressors.” The aim of His death, resurrection, ascension, and eternal life, is towards the sinful sons of men. His death has brought pardon, but it cannot be pardon for those who have no sin for pardon is only for the guilty. He is exalted on high “to give repentance,” but surely not to give repentance to those who have never sinned, and have nothing to repent of. Repentance and remission both imply previous guilt in those who receive them: unless, then, these gifts of the exalted Saviour are mere shams and superfluities, they must be meant for the really guilty. From His side there flowed out water as well as blood-the water is intended to cleanse polluted nature, then certainly not the nature of the sinless, but the nature of the impure; and so both blood and water flowed for sinners who need the double purification. To-day the Holy Spirit regenerates men as the result of the Redeemer’s death; and who can be regenerated but those who need a new heart and a right spirit? To regenerate the already pure and innocent were ridiculous; regeneration is a work which creates life where there was formerly death, gives a heart of flesh to those whose hearts were originally stone, and implants the love of holiness where sin once had sole dominion. Conversion is also another gift, which comes through His death, but does He turn those whose faces are already in the right direction? It cannot be. He converts the sinner from the error of his ways, He turns the disobedient into the right way, He leads back the stray sheep to the fold. Adoption is another gift which comes to us by the cross. Does the Lord adopt those who are already His sons by nature? If children already, what room is there for adoption? No; but the grand act of divine love is that which takes those who are “children of wrath even as others,” and by sovereign grace puts them among the children, and makes them “heirs of God, joint heirs with Jesus Christ.” ~ C.H.
