The devil is not dead

The devil,Christians common enemy, is not dead and cannot die until the appointed time for him when the Lord shall bring his activities to an end for eternal damnation.This is why christians should, as a habit continually keep the devil's activities at bay in their lives without relenting.Do not think at any point in time when you are waging a spiritual warfare against the enemy and principalities,and God grants victory,then you rejoice and go to sleep and stop praying because they think "the devil is dead".Christians need to pray  without ceasing because just like the air surrounds us, the enemy,the devil is moving about looking for careless Christians who are not on guard to attack.
