"Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him who had the power of death, that is, the devil." Hebrews 2:14
By his sufferings, blood shedding and death, our gracious Lord not only made a complete atonement for sin, fulfilled every demand of the law, washed his people from all their iniquities in the fountain of his precious blood, and wrought out and brought in a perfect and everlasting righteousness for their justification, but "through death destroyed him that had the power of death, that is, the devil." It was by the death of the cross that the gracious Lord "spoiled principalities and powers, and made a show of them openly, triumphing over them in it." It is a point little considered, though one of much importance, that the Lord Jesus had, as if personally, to grapple with and overcome the prince of the power of the air, to hurl Satan from his usurped throne, to destroy his works, and overthrow his kingdom; and this not by an act of omnipotent power, but by an act of the lowest weakness, for "he was crucified through weakness."
According to our simple views, we might think that all that was needed to overthrow Satan was an act of omnipotent power. But this was not God's way. The king over all the children of pride, in the depths of infinite wisdom, was to be dethroned by an act of the deepest humility, of the most meek and submissive obedience, of the intensest suffering of God's own beloved Son, as standing in the place of those over whom Satan and death had triumphed through sin. We read that "the Son of God was manifested that he might destroy (literally, 'loosen' or 'untie') the works of the devil." Thus he came, not only to untie and undo all that Satan had fastened and done by traversing, as it were, the whole ground, from the first entrance of sin and death, and, by a course of holy and meritorious obedience, repair the wreck and ruin produced by the primary author of all disobedience, but, as the final stroke, to destroy and put down the disobedient and rebellious prince of darkness himself.
