Final answer:
The missing word in the verse is 'B) Shield.' Faith acts as a protective shield against the attacks of Satan.
Step-by-step explanation:
The missing word in the verse, 'In every battle you will need faith as your shield to stop the fiery arrows aimed at you by Satan,' is 'B) Shield.'
This verse is a metaphorical reference to the spiritual battle against evil and the importance of having faith as a protective shield. Just like a physical shield, faith acts as a defense and protection against the attacks of Satan. It helps to deflect and block the fiery arrows of temptation, doubt, and fear that Satan uses to try to weaken our faith.
