Take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand. Ephesians 6:13 (NKJV)
Proper dress is essential. If you’re a football player, you put on shoulder pads. If you’re a state trooper, you wear a uniform and a gun. If you’re a Christian, you are in a battle against an unseen foe, and you don’t dress casually for warfare. The suit looks like this:
The loins of truth. This is the truth of what God’s Word says about you. God accepts you unconditionally. You are His child. You belong to Him forever. This is your guard against deception.
The breastplate of righteousness. This is your standing with God. He has declared you innocent of all sin through the blood of Christ. This is your guard against guilt.
The preparation of the gospel of peace. This is your means for sharing the good news of salvation with others, bringing them the offer of peace through Christ; it is your guard against complacency and self-centeredness.
The shield of faith, helmet of salvation, and sword of the Spirit. These work together as your commitment to and reliance on the Word of God for every circumstance—refusing to yield to temptation or to falter in trials.
