Read Ephesians 6:14-16 with 1Peter 1:1-9
The imagery the Spirit uses for each piece of holy armour is significant. Faith is symbolized as a shield: its purpose is to cover the whole man; it is constructed that, even before meeting the enemy in battle, fiery arrows are shot, and this shield can quench them. So it is with faith. "Above all" take up the shield of faith!
