We wrestle with principalities and against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places and, therefore, we should always seek the power from Lord Jesus Christ to overcome them. We should, therefore, stand with our loins girt ever ready to fight these evil forces with the help of help and in the name of Lord Jesus Christ, who defeated Satan at the cross. The principalities and powers are superhuman devilish agencies and demonic powers as we read in Romans 8:38 Ephesians 3:10; Ephesians 6:12 Colossians 1:16; Colossians 2:10, 15. We must know our enemy. Our enemy is not any man in his flesh but the devil, the Old Dragon that deceived Eve in the Garden of Eden. Satan is defeated foe but still alive with his limited power ever casting doubts in the minds of believers in Christ. This book explains the weapons of war that a believer has to put on to be successful in the combat against the evil forces from Satan, temptations from him, and subdue him in the battle against him.
