In Paul's letter to the Ephesians, he informs us that our battle is not against flesh and blood. Instead, we battle against the wiles of the Enemy, and wrestle "against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places." Our first line of defense is "to be strong in the Lord and the power of His might." To take this firm stand, we must understand who we are in the Lord as well as recognize the power of his might. This study takes a unique approach, using Paul's conclusion to the letter as a guide to studying the rest of the text.
