The shield of faith is part of the armor of God described in Ephesians 6:10–17. It provides protection for Christians from Satan's schemes and the flaming arrows of the evil one, which are evil thoughts injected into one's mind. Faith is how believers can extinguish these arrows and overcome temptation by trusting that God's promises are true. The shield of faith reminds Christians that through faith in Jesus, they have been redeemed and have nothing to fear from accusations of Satan or the world.
