Paul then instructed the believers to “Put on the whole armor of God” (Ephesians 6:11a NASB). The Roman soldiers, dressed in their full armor, provided a wonderful picture of the spiritual armor which each believer is to put on. It is not automatic. We must “put on the full armor, so that you will be able to stand firm against the schemes of the devil” (Ephesians 6:11 NASB). Paul established the reason for this absolute necessity because “For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places” (Ephesians 6:12 NASB).
Ephesians 6:14–17 describes each piece of the armor we are to put on:
- Gird your loins with truth. It is the truth that holds all the armor in place.
- Put on the breastplate of righteousness. It is the righteousness of God that will protect our hearts.
- Put on the shoes of the gospel of peace. Only a walk of peace can protect us from the enemy’s attacks of “anxiety and worry.”
- Take up the shield of faith. It is the shield of faith that protects us from all the enemy will throw at us. The Roman soldiers linked their shields together creating a solid wall against what their enemy was throwing at them. We need each other beloved! As we walk in a covenant relationship, the enemy is less likely to get through and defeat us.
- Pick up the Sword of the Spirit. One needs a sword, which is offensive. The Sword of the Spirit which has been provided to us is a two-edged sword. It is the two-edged Word of God. The first edge is the side that convicts, cleanses, and heals the believer. The other edge is wheeled against the enemy to set captives free and bring them to our benevolent King who forgives, breaks off strongholds and anoints for service in His army of saints.
