Summary: We utilize what God has issued us for the conflict. We need protection. Which breastplate are we trusting? Our own, or Christ's righteousness? Don't go to war without the Breastplate of Righteousness.

In today’s military, a critical element of force protection is body armor. The Army issues Kevlar flak vests to soldiers to protect their upper body. DuPont, the manufacturer, claims they’re lightweight, but I’d disagree. It doesn’t take long to feel weighed down. Nonetheless, you wouldn’t want to go to war without one. Kevlar flak vests offer protection from ballistic threats and thermal protection from blasts and fire. They are a modern-day breastplate.

In Bible times, a soldier’s breastplate was usually either a coat of chain-mail or a molded metal chest plate that covered one’s front and back torso, from the neck to the upper thighs, safeguarding vital organs from injury. Paul tells us to stand--and we can--with proper protection: with the “breastplate of righteousness”, an image taken from Isaiah 59:17.

“Righteousness” is doing what is right in God’s eyes; it is purity, holiness, and integrity. It is being of one mind with God. It is ceasing to walk in darkness because we have the light of Christ. Paul wants us to take this spiritual resource and put it to use in our day-to-day battles. Soldiers of God are issued righteousness, which is put to our account. We have none of our own. When we turn to Christ, our sins are no longer held against us; we are given the righteousness of Christ. His purity is credited to us; it becomes part of us. And righteousness is imparted as the Holy Spirit sets us apart and shapes us into the kind of soldiers we need to be.

“Righteousness” means we sustain a disciplined, responsible life. Paul tells the Corinthians, “I keep control of my body and bring it into subjection” (I Cor. 9:27). A soldier is a “lean, mean fighting machine” who has gone through intensive training and drills, maintaining high standards of fitness. In the same way, soldiers of God follow after spiritual-mindedness. Proverbs 11:4 states, “Wealth is worthless in the day of wrath, but righteousness delivers from death.” And Jesus declared in Matthew 5:6, “Blessed are those who hunger and thirst for righteousness, for they shall be filled.”

The word “Righteousness” today is almost always used with a negative connotation. People who are “righteous” are considered rigid and puritanical. “Righteous” in Scripture means to be “up to standard”, presentable (Tim Keller). Soldiers stand at attention in formation while their First Sergeant inspects their uniforms and makes corrections. If any aspect of their uniform isn’t squared away, be sure there will be push-ups! Whether you’ve served in the military or not, no one wants to be unpresentable; no one wants their flaws to show. We want to be pleasing in the eyes of others--parents, spouse, friends, employers. Have you ever shown up at an event improperly dressed? It’s mortifying! If you go to battle without protection, it’s fatal.

To be righteous is also to be right with God, doing His will. How can we ever live up to God’s standards? We can’t even live up to our own! Adam and Eve were presentable to God until they chose to sin, and then they felt shame and covered themselves with fig leaves. We are made right with God by God. This happens by God’s initiative. Righteousness is freely given to us. A breastplate of fig leaves won’t do.

Young people are often given a rosy, unrealistic picture of the military by recruiters. Nearly every week a soldier said, “Chaplain, my recruiter lied to me!” These new recruits report to Boot Camp wondering where the dorms are, and the PX, the NCO Club, the “dining facility”, the Rec Center, the movie theater…and are in for a rude awakening. It is the job of Drill Instructors to turn soft civilians into soldiers who are disciplined and dedicated…or drum them out of the military before Uncle Sam spends too much money on their training. In a similar way, Jesus warned eager would-be disciples to “count the cost.” Do we accept the terms of enlistment for being a Christian soldier?

The Breastplate of Righteousness guards the heart against attack. In our increasingly godless world we’re up against an onslaught of secular ideology hostile to biblical values. And the devil seeks to disarm us through temptation, fear and discouragement. In this war with two fronts there is no truce, only unceasing warfare. We should never assume we’re beyond the reach of this world-and-devil enemy coalition.

We are called to face the enemy. But we’re not waging a private battle; the battle is not ours, but the Lord’s. And it is not about personal honor, but the honor of God. A fellow retired Army chaplain, Lee Vermont, writes that “The heart of spiritual warfare could best be summarized as resistance and proclamation” (Tactics of Truth). We resist the values and lies of our fallen world and proclaim the truth of God’s word. So “righteousness” is not something we admire; it is something we do. We utilize what God has issued us for the conflict. If we’re not striving towards righteousness we’ll be easy targets for the enemy.

The human heart is the center of holy and unholy passions. We need to guard our hearts from temptations and from the evils we may do to ourselves. We need to remain on guard, on the watch, always. After conversion, we still sin. The difference is, while we used to be sinners running after sin, we are now sinners running from sin. How does righteousness protect us? By enabling us to say “no” to sin. The devil is quick to accuse and remind us of our sinfulness and unworthiness. He would like to defeat us by hopelessness and despair. When the devil reminds you of your past, remind him of his future.

We need protection. Dangers are all around us: “Buy this, try that, listen to this idea, go for it, enjoy yourself, live it up, live for today.” Our armor is not our own self-righteousness. Neither is it emotion or experience. We don’t forge our own armor; we cannot make ourselves holy. Jesus said “Without Me you can do nothing” (John 15:5). “Our hope is built on nothing less than Jesus’ blood and righteousness.” He makes us presentable; holiness is a gift from Above. John MacArthur writes: “If you think you can earn your way into Heaven on your own, by living a good life, you are wearing the wrong breastplate.” One made of cardboard! One that leaves us exposed. Paul writes in Romans 13:14, “Put on the Lord Jesus Christ and make no provision for the flesh.” Nothing can penetrate the all-sufficient armor given us!

The Kevlar Survivors Club recently inducted its 3,000th member, Corey Grogan, a police officer who in the line of duty was struck twice in the chest by gunfire. The impact knocked him down but he was unharmed.

How do we put on God’s Kevlar? By taking hold of Christ by faith. At the end of our lives, what breastplate do we trust in? Our righteousness, or Christ’s? Through the cross we are made worthy and acceptable. Because of the Cross, terror is terrified. Let’s not be dismayed by evil. God will deliver us. In the meantime, let’s make it our ambition to be as holy as saved sinners can be.
