The Armor of God - Breastplate of righteousness
The soldier’s breastplate was designed to protect his vital organs, but especially the heart. So the Christian’s breastplate of righteousness represents his moral rectitude or his righteous character and conduct. Elsewhere Paul defines this breastplate as “faith and love” (1 Thess. 5:8a). Both truth and righteousness are indispensable equipment to the Christian warrior’s victory. Against these the devil can never prevail. Truth and righteousness are primarily defensive items of the spiritual warfare.
The breastplate of righteousness. This covers the heart. It means having a good conscience. Not merely knowing that we are the righteousness of God in Christ, that we are righteous because we believe on Him, but it means a consistent walk with our position in Christ and the relationship into which the Grace of God has brought us. It is again the walk, worthy of our vocation, obedience to the exhortations of the preceding chapters. Covered by this the devil cannot touch us. Such practical righteousness “love out of a pure heart and of a good conscience and of faith unfeigned” keeps us in the realization and enjoyment of our relationship to God, in the fellowship with the Father and the Son. How often we fail in having on the breastplate of righteousness. Then we must seek restoration by confessing our sins (1 John 1).
and having on the breastplate of righteousness—The righteousness of a spotless purity, in which Christ will present us faultless before God, through the merit of his own blood. With this breastplate our Lord is described, Isaiah 59:17. In the breast is the seat of conscience, which is guarded by righteousness. No armour for the back is mentioned. We are always to face our enemies.
There is the breastplate of righteousness. When we are clothed in righteousness, we are impregnable. Words are no defence against accusations, but a good life is. Once, a man accused Plato of certain crimes. ‘Well then,’ said Plato, ‘we must live in such a way as to prove that his accusations are a lie.’ The only way to meet the accusations against Christianity is to show how good a Christian can be.
Righteousness is the conformity or obedience to a standard or obligation that is normally understood to be morally good, such that the expectations and requirements of relationship toward God and neighbor are satisfied.
