But as he hangs ‘twixt earth and skies,

He gives their prince a fatal blow,

And triumphs o’er the powers below.

~ Isaac Watts

The most frequent metaphor Scripture uses to describe daily Christian life is the metaphor of war:

“Lay aside the deeds of darkness and put on the armor of light.” (Ro. 13:12)

“Put on the full armor of God, that you may be able to stand firm against the schemes of the devil.” (Eph. 6:11)

“Suffer hardship with me, as a good soldier of Christ Jesus.” (2Tim. 2:3)

“Fight the good fight of faith…” (1Tim. 6:12)

“The weapons of our warfare are not of the flesh, but divinely powerful for the destruction of fortresses.” (2Cor. 10:4)

“The kingdom of heaven suffers violence, and violent men take it by force.” (Mt. 11:12)

And so on.

Warfare is a constant theme running throughout Scripture. The Israelites’ bloody conquest of the Promised Land is a grand typological foreshadowing of how the Christian in the New Covenant gains his promised eternal rest by violence.

“Wait a second…violence?” you ask. “I thought the gospel was a message of peace?”

And it is. But we must be clear about whose peace we mean. Jesus said “Peace I leave with you; My peace I give to you; not as the world gives, do I give to you” (John 14:27). Gospel peace is not the promise of a quiet life in the country, or a vision of a better world, free from poverty and guns. The peace of the gospel is peace with God; where we, who are by nature children of wrath, enemies of God, deserving only of eternal hell and torment, are reconciled to God the Father through the shed blood of His Son.

Like I said, violence. Jesus made peace for us by laying down His life, “Like a lamb that is led to slaughter” (Isa. 53:7), a perfect and willing sacrifice—violence many of us have come to understand and appreciate.

But there’s much more to it than that. Jesus also made peace for us by conquering. On the cross, He “disarmed the rulers and authorities…[and] made a public display of them, having triumphed over them” (Col. 2:15). He bound the strong man, Satan, and is even now plundering his house (Mt. 12:22-29).

More violence. But this time violence inflicted by Jesus, instead of received by Him.

Today, most of us have never considered this aspect of the gospel. It would never occur to us that Jesus of Nazareth was in any way a violent man. And consequently, we have absolutely no grid for understanding the very real sense in which we ourselves are commanded by God to be men of violence.

Again you interject, “I thought the gospel was a message of peace?” And once more I respond, yes absolutely it is! Hallelujah! And amen! But the peace promised us in the gospel is a peace that instructs us to “put on the full armor of God,” to “stand firm against the schemes of the devil,” to “suffer hardship…as good soldiers,” to be “very strong and courageous,” to wield the “Sword of the Spirit,” to be “on guard” so that no one takes us “captive through philosophy and empty deception”—the peace of the gospel commands us to fight!

It used to be that such gospel imperatives were the frequent topic of both preaching and teaching. It used to be that the church encouraged herself to militancy in both her songs and her prayers. So what ever happened? Why can’t you remember ever singing anything like this in Christian worship:
