Paul spends much of Ephesians telling us how to live in a way that is pleasing to God. In Ephesians 4, he calls us to unity and holiness, and to the understanding that even though we are all different and have different purposes, we are all part of one body under Christ. Ephesians 5 continues the theme of holiness and living as children of light. In the last verses of Ephesians 5 (Ephesians 5:22-33) and the first verses of Ephesians 6, (Ephesians 6:1-9) Paul gives us advice for our family relationships, and for our work relationships. He also tells us what our attitude towards our jobs should be, including if we are the employer and not just the employee. But Paul knows that it is not as easy as all that! Paul understands very clearly that we are in a constant spiritual battle. Since creation, God has provided us with a choice, to choose Him or the world, and He has been very gentlemanly about letting us make that choice.(Revelation 3:20) Satan, on the other hand, is working very hard at winning us over to his side, and he will use any means available. (II Corinthians 11:14, I Peter 5:8) We need to realize that our struggles on this earth are not with things, or circumstances or with each other. They are all part of a battle in the spiritual realm. (Ephesians 6:12)
The good news is that we don’t have to fight this battle alone. Hallelujah! We can rely on the strength of God’s power and His armour. Just as a Roman soldier was clothed in a suit of armour, we can be clothed with God’s spiritual armour. If we put on the full armour of God we will be able to stand against our enemy’s schemes and attacks, and to be left standing when all is said and done. What does God’s armour consist of?
1. The Belt of Truth: A Roman soldier used a belt to hold his garments together and to attach his armour. It made it easier for him to be able to move without tripping over his tunic. Wearing the belt of truth represents not only knowing and believing God’s truth, but also living a truthful life, thus allowing us easier movement without tripping over our words. Knowing and practicing the truth will give us protection against the father of lies. (John 8:44)
2. The Breastplate of Righteousness: We were declared righteous when we accepted Christ’s sacrifice as the substitution for our sins, (Romans 4:5, Romans 10:10) but again, Paul is referring here to the practical, daily actions of believers. We need to act in a way that no one can make an accusation against us, a way that protects our hearts.
3. Preparation That Comes From the Good News of Peace: You can be ready for whatever comes your way if you place your trust in the all-powerful God of peace. The Greek word translated as preparation here indicates to be on a firm footing. It refers to the stability that you get from the gospel of peace that allows you to stand steadfast in the face of battle.
4. The Shield of Faith: Roman soldiers had large shields that would interlock together so that they could advance with a wall of protection before them. They were coated in leather that was soaked in water so that flaming arrows would be extinguished. Satan is certainly attacking us with fiery arrows, and it is our faith that will protect us from them. Since we cannot know when or how these fiery arrows will come, constant faith is absolutely essential.
5. The Helmet of Salvation: The helmet of salvation is a gift from God that protects our heads and our minds. God does not require our faith to be blind. We are encouraged to question and to understand. We need to protect our minds from Satan’s schemes, by growing in grace and knowledge of the Lord Jesus Christ. (II Peter 3:18)
6. The Sword of the Spirit: The sword used by Roman soldiers was double-edged so that it could cut in both directions and sharp enough to pierce armour. But the Word of God is sharper than any double-edged sword, and able to judge the heart. (Hebrews 4:12) It is by being very familiar with the Word of God that we will be able to discern what is right and defend ourselves from Satan’s attacks. Satan also knows the Word of God, and he uses it to his advantage--not fully and out of context. (Matthew 4:5-7) If we are to defend ourselves as Jesus did, we must know the Word of God as Jesus did.
Add to all of these prayer for all the saints. If we are praying for each other, we will be alert to the needs and struggles of our fellow warriors. This is not a battle that we can fight ourselves. Remember that Paul’s words here come at the end of a passage about unity, and being one body. Working together as one body, with God’s strength, we can win the battle in the spiritual realm.
