Paul uses the analogy of the Roman armour because in his day the Romans had an advanced system of warfare.
The Romans perfected a light, full torso armour which provided protection for vital areas. With this armour they could advance towards the enemy being protected from any retaliatory weapons.
In the same way soldiers in the Lord’s army need to be dressed in spiritual military armour in order to battle the powers of darkness.
The breast plate of righteousness is one part of the armour of God.
The Roman soldier’s breastplate was called a cuirass. It was molded to fit over the chest with another part for the back.
The breast plate was protection for the vital organs. One being the heart.
The breastplate of righteousness is to be worn to protect the heart.
In Hebrew the Old Testament word for heart heartlêbâb, lêb, lêbâb,
is the intellect, emotions, and understanding.
In Greek the New Testament word for the heart is kardia which also refers to the mind. (thoughts, feelings)
The breastplate or protection for the mind is a breastplate of righteousness. In other words the Christian mind must be protected by the Lord’s righteousness.
What is righteousness?
In the Old Testament righteousness tsedâqâ is moral virtue and justice.
The New Testament defines righteous dikaiosunē as equity or justification.
To be justified dikaioō is to render innocent, to free.

This is done by putting on the breast plate of righteousness. Being conscious of our justification provided by Jesus Christ.
Proverbs 4:23 tells us to keep or guard nâtsar our heart. lêb

With the breast plate of righteousness our minds are guarded from enemy attacks.
When the devil came to Jesus to tempt him with lies Jesus referred to the word of God as his defense. “It is written.”
Out of the heart or mind are the issues or source of our life. Proverbs 4:23
As we put on the breastplate of righteousness we can see ourselves clothed in Jesus Christ’s righteous. Our minds filled with God’s word will keep us from the trickery of the devil.
