Jesus Will Crush Satan.
And the God of peace will crush Satan under your feet shortly. The grace of our Lord Jesus Christ be with you. Amen. Romans 16:20 NKJV
Because of the promise of God, that we shall have victory at last, which is given to quicken and encourage, not to supersede, our watchful cares and vigorous endeavours. It is a very sweet promise: The God of peace shall bruise Satan under your feet.
The titles he gives to God: The God of peace, the author and giver of all good. When we come to God for spiritual victories, we must not only eye him as the Lord of hosts, whose all power is, but as the God of peace, a God at peace with us, speaking peace to us, working peace in us, creating peace for us. Victory comes from God more as the God of peace than as the God of war; for, in all our conflicts, peace is the thing we must contend for. God, as the God of peace, will restrain and vanquish all those that cause divisions and offences, and so break and disturb the peace of the church.
The blessing he expects from God-a victory over Satan. If he mean primarily those false doctrines and seducing spirits spoken of before, of which Satan was the prime founder and author, yet doubtless, it comprehends all the other designs and devices of Satan against souls, to defile, disturb, and destroy them, all his attempts to keep us from the purity of heaven, the peace of heaven here, and the possession of heaven hereafter. Satan tempting and troubling, acting as a deceiver and as a destroyer, the God of peace will bruise under our feet. He had cautioned them before against simplicity: now they, being conscious of their own great weakness and folly, might think, "How shall we evade and escape these snares that are laid for us? Will not these adversaries of our souls be at length too hard for us?" "No," says he, "fear not; though you cannot overcome in your own strength and wisdom, yet the God of peace will do it for you; and through him that loved us we shall be more than conquerors."
The victory shall be complete: He shall bruise Satan under your feet, plainly alluding to the first promise the Messiah made in paradise (Genesis 3:15), that the seed of the woman should break the serpent's head, which is in the fulfilling every day, while the saints are enabled to resist and overcome the temptations of Satan, and will be perfectly fulfilled when, in spite of all the powers of darkness, all that belong to the election of grace shall be brought triumphantly to glory. When Joshua had conquered the kings of Canaan, he called the captains of Israel to set their feet upon the necks of those kings (Joshua 10:24), so will Christ, our Joshua, enable all his faithful servants and soldiers to set their feet upon Satan's neck, to trample upon, and triumph over, their spiritual enemies. Christ hath overcome for us; disarmed the strong man armed, broken his power, and we have nothing to do but to pursue the victory and divide the spoil. Let this quicken us to our spiritual conflict, to fight the good fight of faith-we have to do with a conquered enemy, and the victory will be perfect shortly.
The victory shall be speedy: He shall do it shortly. Yet a little while, and he that shall come will come. He hath said it, Behold, I come quickly. When Satan seems to have prevailed, and we are ready to give up all for lost, then will the God of peace cut the work short in righteousness. It will encourage soldiers when they know the war will be at an end quickly, in such a victory. Some refer it to the happy period of their contentions in true love and unity; others to the period of the church's persecutions in the conversion of the powers of the empire to Christianity, when the bloody enemies of the church were subdued and trampled on by Constantine, and the church under his government. It is rather to be applied to the victory which all the saints shall have over Satan when they come to heaven, and shall be for ever out of his reach, together with the present victories which through grace they obtain in earnest of that. Hold out therefore, faith and patience, yet a little while; when we have once got through the Red Sea, we shall see our spiritual enemies dead on the shore, and triumphantly sing the song of Moses and the song of the Lamb. To this therefore he subjoins the benediction, The grace of our Lord Jesus Christ be with you-the good-will of Christ towards you, the good work of Christ in you. This will be the best preservative against the snares of heretics, and schismatics, and false teachers. If the grace of Christ be with us, who can be against us so as to prevail? Be strong therefore in the grace which is in Christ Jesus. Paul, not only as a friend, but as a minister and an apostle, who had received grace for grace, thus with authority blesses them with this blessing, and repeats it, v. 24. - Matthew Henry
