May I frankly say that anyone trusting in “spiritual armor” as a thing in and of itself is going to fail miserably. Anyone relying upon a faith-formula or a spiritual warfare method is going to see both the formula and the method eventually meet with defeat. Why? Because God has not given us a formula or a method: He has given us His Son.
He does not give us a ritual or ceremony to follow, He says, “Put on the Lord Jesus.” Having the Lord Jesus, I have the Whole Armor of God. It is not necessary to ask for each piece of armor, or to confess anything, or to do anything. It is only necessary, having put on the Whole Armor of God, to “stand therefore.” It is only necessary, having put on the Lord Jesus, to abide in Him.
