Guarding Your Mind And Emotions

John MacArthurby John MacArthur

“Stand firm therefore . . . having put on the breastplate of righteousness” (Eph. 6:14).

True righteousness begins with a right relationship with God.

A Roman soldier would often engage his enemy in hand- to-hand combat. At such times, the weapon of choice was the short sword, with which he sought to penetrate his opponent’s vital organs. For his own protection he wore a molded metal breastplate that extended from the base of his neck to the top of his thighs. It helped deflect any attacks aimed at his heart and abdomen.

The Roman breastplate has great symbolism in Paul’s analogy because to the Jewish people, the heart represented man’s mind and thinking processes; the intestinal area or bowels represented the seat of feelings and emotions. Proverbs 23:7 says, “As [a man] thinketh in his heart, so is he” (KJV). Jeremiah 17:9 says, “The heart is more deceitful than all else and is desperately sick; who can understand it?” Jesus added, “From within, out of the heart of men, proceed the evil thoughts” (Mark 7:21).

During spiritual warfare, Satan’s primary attacks target your thinking and emotions. If he can condition you to think and feel contrary to God’s Word, he has won a significant victory. That’s why he attempts to fill your mind with lies, immorality, false doctrine, and half-truths. He tries to blur the line between righteousness and sin by surrounding you with evil influences that increase your tolerance for sin. He clothes offensive sin in the blinding garment of entertainment. He puts it to music and masks it in humor to confuse you and deaden your spiritual senses. Satan wants to corrupt your emotions and draw you into sinful desires.

Putting on the breastplate of righteousness begins with a right relationship with God, who is the source of true righteousness. From that relationship flows the commitment to cultivate righteousness in your own life by learning and applying His Word. Therein lies the protection you need to safeguard your mind and emotions from satanic deceptions.
