When we are under spiritual attack we have one form of defense:
Our worship.
And what is our ammo:
Our thanksgiving!
Check this out:
"After consulting the people, Jehoshaphat appointed men to sing to the Lord and to praise him for the splendor of his holiness as they went out at the head of the army, saying:
“Give thanks to the Lord,
for his love endures forever.”
~ 2 Chronicles 20:21
