The perfect obedience of Christ, and His meritorious death, were both necessary as the ground of a sinner's justification. Neither would have been sufficient without the other. His obedience would not answer without His death; for the law which had been broken must be honored; and the penalty which had been incurred by the sinner must be endured by the Substitute. Neither would His death answer without His obedience; for it is the obedient, and not the punished, that the law justifies; he who keeps the precept, and not he who endures the penalty. It is only by satisfying both claims on our behalf, that Christ "of God is made unto us wisdom, and righteousness, and sanctification, and redemption."
