We're all involved in spiritual warfare—no matter our standing in life—and like a predator, our enemy goes after the weak. We must be strong in the Lord and wield the shield of faith, which extinguishes all the fiery arrows of the enemy. These aren't just arrows that kill, but they hit and set the whole body aflame. That can be lust, resentment, anger, worry, etc. Faith produces an assurance of future things to happen and a certainty that things unseen are just as real, or more real in some cases, than what we can see with our eyes. Faith comes by God's word being revealed to our hearts. Lord, increase our faith!
