Put on the helmet of salvation, the breastplate of righteousness, the belt of Truth, the shoes for the preparation of the Gospel of peace, above all else take up the shield of faith so that you can quench all the fiery darts of the wicked and take up the Sword of the Spirit which is the Word of God.
The way I understand these scriptures, is that they are not saying we don't battle in a physical sense. But that the underlying cause for the battle is always a spiritual one. This is where the real battle lies. For example, the war in Iraq. There is a physical battle going on, but the underlying cause for the battle in Iraq is a spiritual one. This is why it is so very important for us as Christians to make sure that we fight in this battle spiritually and pray for our troops that are over there.
Only prayer and the speaking of God's Word in faith and in the power of the Holy Spirit is what brings forth the ultimate victory every time. Eventually the enemy will be totally defeated in this world. Just read the book of Revelation. Jesus wins!
Right now we are experiencing spiritual warfare as well as physical warfare. We are not defeated if Jesus is Lord of our lives, placing our trust in Him and lining our lives up with what the Word of God says about us. When we are spiritually clothed with the armour of God we are actually clothed with Christ Jesus. He is our Armour. For example when we have on the helmet of salvation, we are covered with the salvation of Jesus Christ. It is by and through Jesus that we are saved. When we have on the breastplate of Righteousness we are clothed in the righteousness of Christ Jesus. In and of ourselves our righteousness is as filthy rags, but the Word of God says that through salvation we have become the righteousness of Christ Jesus. When we gird ourselves with the belt of Truth, spiritually speaking we gird ourselves with Jesus, for He is the Truth. Jesus is the Way, the Truth and the Life and no man comes unto the Father except through Jesus. And when we know the Truth (Jesus), the Truth will set us free. Whom the Son sets free is free indeed. When we have on the shoes for the preparation of the Gospel of Peace, we are wearing the Good News upon our feet, and every where we go we bring the Gospel which is the Good News. By the way the Good News is salvation through Christ Jesus. So He is the Good News! And when we cover our feet with Him we can have perfect peace which passes understanding no matter where we are at. He will keep you in perfect peace who's mind is stayed on Him. Above all else take up the shield of Faith. Jesus is our Faith. We believe by Faith in the Son of God. When our Faith is in Him the fiery darts of the enemy will be quenched and will never penetrate our hearts. Our wounds would be less if we would only lift up our shield of Faith (Hold up Jesus)! It is in the Name of Jesus that every knee will bow and every tongue will confess that Jesus Christ is Lord. The enemy is defeated. Take up the Sword of the Spirit which is the Word of God. Jesus is the Word. In the beginning was the Word the Word was with God and the Word was God and the Word became flesh and dwelt among us! Yes! that would be Christ Jesus Himself.
When we clothe ourselves in Jesus (who is the Armour of God) the enemy doesn't have a chance. Ha Ha! And the Word of God says that God laughs at the enemy! The enemy is small in comparison to our God. One day we are going to find out just how scrawny he really is. It will be unbelievable, for the Word of God says, that the people will ask, "Is this he who tormented the nations?"
May we get a spiritual vision of the enemy so that we can laugh at his attacks even now as we stand clothed in Jesus!
For He (Jesus) that is in you is greater than he (enemy) that is in the world!
And God has made us more than conquerors and an overcomer in Christ Jesus!
