We’d be fools to walk into a battle unarmed, wouldn’t we? We would never go to the front line without some sort of armor or weapon. Well, we are in a battle, though our battle is not of this world. It’s a spiritual battle of principalities and powers. It’s against the devil who has a well laid out plan against us. He is skilled and cunning in deceit, trying to slander the name of the Lord. This is why we need the full armor of God. It’s God’s battle and He will have the victory.
