How do we know our faith is strong enough to be a protective shield from the enemy? We know because God’s Word says that it is our faith in God and His faithfulness to us that becomes a shield for us. God said to Abram, “Do not be afraid, Abram. I am your shield, your exceedingly great reward” (Genesis 15:1). When we put our faith in God and His Word, He is our shield and defense. Now that is something we can have faith in.
