When we are talking about the armor of God, the Biblical text that comes to everyone’s mind is Ephesians 6:11-17 “Put on the whole armor of God, that you may be able to stand against the wiles of the devil. 12 For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places. 13 Therefore take up the whole armor of God, that you may be able to withstand in the evil day, and having done all, to stand. 14 Stand therefore, having girded your waist with truth, having put on the breastplate of righteousness, 15 and having shod your feet with the preparation of the gospel of peace; 16 above all, taking the shield of faith with which you will be able to quench all the fiery darts of the wicked one. 17 And take the helmet of salvation, and the sword of the Spirit, which is the word of God.”
The first thing we need to realize is that the armor is God’s, not ours. I have heard sermons preached that make this sound like it’s a gift God has given to you but it’s not. It’s always has been HIS ARMOR. Why is that an important distinction, you may be wondering? The answer comes when we look at biblical history.
In Bible times it was customary for kings to choose a champion to fight for them in battle. The champion would wear the king’s armor and any battles that were won by the champion were attributed to the king, not to the warrior in the king’s armor. This was the reason that Saul tried to clothe David in his armor in 1Samuel 17:38&39 “So Saul clothed David with his armor, and he put a bronze helmet on his head; he also clothed him with a coat of mail. 39 David fastened his sword to his armor and tried to walk, for he had not tested them. And David said to Saul, ‘I cannot walk with these, for I have not tested them.” So David took them off’.”
God would not allow David to wear Saul’s armor. God made him uncomfortable in Saul’s armor because David was God’s champion, not Saul’s. Why is this of importance to us? When we put on the armor of God we are operating as God’s Champion in the world. We put on His armor and fight, for God, against His enemies in the spiritual battle for the people of this world.
It is for this reason that Paul says, “We do not wrestle against flesh and blood but against principalities, against powers against the rulers of the darkness of this age, against spiritual host of wickedness in heavenly places.” He is reminding people that once you have put on God’s armor, you only fight against the armor owner’s enemies. Furthermore, the armor’s owner gets the credit for every victory you accomplish.
