Ephesians 6:16 In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one.
The truth is we are only half-way. Without the remaining 3 pieces we are still only half-covered. And who would go into battle, or even into daily life half-dressed?
So the next weapon we take up in addition to all the above is “the shield of faith”. The shield of faith is essential to lift over your head and heart when the enemy’s arrows from hell are thrown at you. For example the arrow of an “evil foreboding”. Have you ever had a thought that something bad is going to happen to you or a loved one? That thought is called an evil foreboding (see Proverbs 15:15 AMP). It is a thought from the pit of hell. Choosing to believe the thought is like letting the shield of (godly) faith drop, and allowing the arrow of that “evil foreboding” to penetrate your soul. But the Christian who takes up the shield of faith chooses to believe the truth over lies and keeps holding up the shield until any flaming arrow has been extinguished.
As Martin Luther said,
“You can’t stop the birds from flying over your head, but you can stop them from nesting in your hair.”
We all have a choice as to what arrows we allow. We are given the shield of faith to extinguish them all. We sing the Song of Solomon: “Catch for us the foxes, the little foxes that ruin the vineyards, our vineyards that are in bloom.” (SoS 2:15).
Faith will keep us free.
