The word mercy in the Old Testament is the Hebrew word for grace. Praise the Lord, for His grace endures forever. His grace is sufficient for you. It surrounds you like a shield when it seems like your enemy has you surrounded. Praise Him with a loud voice, singing “Praise the Lord, for His mercy and grace and favor endures forever”. Make a declaration of your victory. It’s your praise that stills the avenger. Sing! Sing! Sing!
