Ephesians 6 reminds us to be strong in the Lord by putting on the full spiritual armor of God to stand against the enemy. We are told to stand our ground by first putting on the belt of truth and then the full armor including breast plate, shoes, shield, helmet, and sword.
Each piece of armor is provided by God to allow you to stand as you are “not fighting against flesh-and-blood enemies, but against evil rulers and authorities of the unseen world, against mighty powers in this dark world, and against evil spirits in the heavenly places.” Ephesians 6:12
God provides the armor as a gift, but you need to put it on daily in order for it to serve its purpose. If not, it is like owning a raincoat and umbrella and forgetting to put them on for protection as you walk in a rainstorm.
God's belt of truth is the most important piece or armor. In Roman times, the belt was important to secure the soldier's tunic and had a place to hold their sword. Jesus is the "way, truth, and the life." John 14:6 and through Him you come to God. In accepting Jesus as your Savior, the Holy Spirit lives in you and will provide gentle nudges to discern truth.
The Breastplate of Righteousness protects you from the condemnation of the enemy. In Roman times, breastplates protected a soldier heart and vital organs. As salvation protects the head, righteousness protects the heart. In Jesus Christ, you are righteous because He gave his life as a sacrifice for you on the cross. The blood of Jesus and his righteousness covers all your sin. Think of putting on righteousness as wearing a royal robe provided to you by Christ.
Shoes allow for sure footedness, even on shaky ground. God's shoes are Gospel shoes of peace. When you meet people in the peace of Jesus Christ and share your testimony, you will be able to stand firm and defend the Gospel.
Shield of Faith: The shield is your first line of defense against the enemies fiery darts of doubt, deception, and discouragement which are meant to destroy your faith. Without faith in God you are likely to give up on believing the truth of who you are in Christ and perhaps your walk with Jesus.
The Helmet of Salvation: protects your mind which is the major battleground. The enemy wants you to believe you are not worthy of salvation. Don’t listen to those lies! Pray and declare the blood of Jesus over your mind. Put on the mind of Christ and take captive thoughts of guilt, shame, and doubt. You cannot earn salvation. When you accepted Jesus as your Savior, you became His.The price has been paid in full; the helmet reminds you of that and protects you. Nothing can take you from Jesus.Your identity and hope are in Him.
Sword of the Spirit: The sword is the Word of God. While all the other pieces of armor are for defense, the sword is an offensive piece of armor. God's Word stands as the final authority over darkness. Speaking the Word of God has great power against the enemy. Jesus gave us an example of this when tempted by the devil in the desert saying "it is written" and wielding the Sword of the Spirit to defeat the enemy.
Put on all of God’s armor so that you will be able to stand firm against all strategies of the devil.
