"Above all, take the shield of faith", Eph. 6:16

 "It is reported of Satan that he says of learned men, "You do always overcome me. When I would exalt and promote you, you lift yourself in humility; and when I would throw you down, you lift yourself up in assurance of faith.' Faith makes the soul invincible; it makes the soul victorious; it leads captivity captive; it binds Satan in chains; it foils him at every weapon; and therefore, above all, labor to be rich in faith."
