The breastplate protects the body's vital organs (heart, lungs, liver, kidneys, gut)—which mirror the five-fold ministry roles (Eph 4:11–13). Since humans are unrighteous , this physical protection symbolizes the need for the Breastplate of Righteousness to sustain the Army of God. Because our righteousness is flawed , we receive imputed righteousness through faith in Jesus Christ , whose perfect obedience acts as an eternal "transplant" for our spiritual life.

Contentment is only found in complete reliance on God which can only be achieved through the pursuit of righteousness and godliness.
