The Breastplate of Righteousness

As Paul continues describing the armor of God in Ephesians 6, he tells us to “put on the breastplate of righteousness” (v14).

I think it’s worth noticing where a breastplate is worn.

It covers the heart.

That’s significant.

Our hearts are vital, and they are vulnerable. What we allow into our hearts, what we believe, what we desire, and ultimately how we live all matter. And while righteousness certainly doesn’t mean that we can somehow make ourselves good enough for God, there is a very real connection between righteous living and protecting our hearts.

The Bible repeatedly calls us to live according to God’s Word—not because obedience earns His love, but because His ways are good. When God says, “Don’t go there,” He isn’t trying to keep us from something good. When He tells us how to live, He is showing us the path of life.

Jesus said, “Blessed are those who hunger and thirst for righteousness, for they shall be satisfied” (Matthew 5:6).

Do we hunger and thirst for righteousness?

Not simply for looking righteous. Not for appearing religious. Not for checking all the right boxes.

For righteousness.

There is a huge difference between pursuing righteousness and falling into legalism.

Legalism says, “If I work hard enough, God will love me more.”

The gospel says, “God already loves me in Christ.”

Legalism says, “If I serve enough, pray enough, give enough, or try hard enough, maybe God will be pleased with me.”

The gospel says that those of us who have put our faith in Jesus Christ alone for salvation have already been adopted into the family of God! We are His children! We are co-heirs with Christ! His love for us is not dependent upon how much or how well we love Him.

We don’t put on the breastplate of righteousness so that God will finally decide we’re worthy of His protection.

We put it on because we belong to Him.

That distinction matters.

Because sometimes, in our desire to flee legalism, we flee righteousness as well.

We become so concerned about being “too religious” and we fool ourselves into no longer taking obedience seriously. We rightly reject the idea that we can earn God’s favor, but then we mistakenly conclude that how we live doesn’t really matter.

But it does.

Not because our obedience earns God’s love.

Because our obedience protects our hearts.

Sin wounds us. Compromise weakens us. Bitterness corrodes us. Lust, pride, greed, dishonesty, unforgiveness, and disobedience leave openings for the enemy to attack.

God’s commands are not chains meant to imprison us. They are wisdom meant to lead us toward life.

The breastplate of righteousness reminds us that there is great value in living rightly—not to become God’s children, but because we already are!

So put it on.

Hunger and thirst for righteousness.

Read God’s Word. Believe it. Obey it. When the Spirit convicts you, respond. When God says “go,” go. When He says “stay,” stay. When He says “forgive,” forgive. When He says “flee,” flee.

Not so that God will love you more.

You couldn’t possibly make Him love you more than He already does in Christ right now.

Live righteously because you are His.

And as you do, guard your heart.

Because the breastplate of righteousness isn’t about earning a place in God’s family.

It’s about living like someone who already has one.
