The Christian who wraps his soul in the objective truth of Scripture shapes his subjective heart for the wiles of war. He takes the divine word deep into his human center, for transformation and joy. He not only searches the Scriptures, but lets the Scriptures search him. He ingests God’s truth both to feed and to condition his soul, subjectively using the objective truth to shape his pliable affections. Slowly, one day at a time, over months and years, this wrapping makes him a vastly different person, far better equipped to both identify truth and embody it.

Given enough time, men and women of principle stand out. After waves of social pressure and the mounting cares of this life, such people are left standing, long after others around them have compromised and toppled.

I’m referring to Christians who don’t play favorites and aren’t partisans of this age. They don’t bend the truth or sweep respectable sins under the rug. Rather, they call Jesus “Lord,” and standing with two feet on his soil, they call “spade” and “evil” to all sides of error and unbelief. Such men and women refuse to cut moral corners, or presume that strategic wrongs can make others right. They shun small compromises and may not stand out at first. But give it time, and their truth and good will be conspicuous (1 Timothy 5:25).

When justice is at stake, such people are not partial to the rich, or the poor. They don’t pick a favorite group, or preferred person, and twist truth and righteousness to fit their darling. Bearing the name of their God, and the Messiah he sent, they judge with impartiality and decide with equity.

And in the spiritual conflict in which we’re engaged, they “stand against the [plural] schemes of the devil” (Ephesians 6:11) that come from every side. They remember that our warfare is spiritual, not “against flesh and blood” (Ephesians 6:12) — and that this war cannot be fought with the weapons of the world.

If such men and women seem to be in short supply in some circles, we might ask, Where do such people come from?

God’s Armor and Ours

“God shows no partiality” is a striking refrain across Scripture, and particularly in the New Testament (Acts 10:34; Romans 2:11; Galatians 2:6; Ephesians 6:9; Colossians 3:25). The implication for God’s people is plain and explicit: do nothing from partiality (1 Timothy 5:21). This is James’s memorable teaching about rich and poor who come to worship: “show no partiality” (James 2:1). “If you show partiality, you are committing sin and are convicted by the law as transgressors” (James 2:9).

But all this truth and righteousness, precious as it is, remains downstream when we come to “the whole armor of God” — and what Paul lists first. Before we start reaching for God’s armor, we should know whose it is, and who wore it first.

Now, some of Scripture’s most magnificent passages can be lost on us through over-familiarity. Such chapters as Isaiah 53 and 1 Corinthians 13 are deservedly famous — and in that due emphasis and celebration, many of us need to move past our dulling acquaintance with them and see them with fresh eyes, and amazement.

The “armor of God” in Ephesians 6 is one of these stunning flourishes. This is Paul at his best, with dazzling Christian creativity, if we might call it that. In one powerfully rhetorical swath, he both pulls together Old Testament references to armor and presses them into Christian use (perhaps even against a Roman backdrop). This is instructive of the range of usages the apostles can make of the Hebrew Scriptures, not only as simple promise-fulfillment, but also illusions and types and patterns and artistic syntheses crafted to serve the holy designs of the authors and needs of their readers. Here the apostle is both poet and pastor.

Iain Duguid makes a compelling case that

each of the pieces of armor has a rich background in the Old Testament, where they describe God’s armor — the armor that God himself dons to rescue his people. The Old Testament, not the Roman legionary, provided Paul with his inspiration — and if we miss this background, we may misinterpret and misapply the various pieces of the armor.

So, we begin with the first — “the belt of truth,” which strictly speaking isn’t armor, defensive or offensive, but pre-armor or under-armor.
