Ephesians 6:16 "Above all, taking the shield of faith, with which you shall be able to quench all the fiery darts of the wicked one."
Your shield of faith, what you really believe and feel is true deep down inside... That is your shield of faith. Your shield of faith is what protects you from the wiles, lies, schemes & trickery of the enemy. Declare truth until it is more real inside than anything else. Make these declarations out loud in faith.
