Unseen warfare is the path of all Christians, it is the Cross we must take up, and it is how we enter the arena of combat for perfection. Every aspect of life is an opportunity for attaining perfection—walking down the street, driving, eating, etc. Thus, the unseen warfare is everywhere—we either take steps towards Christ or steps away from Him. Life is not spiritually stagnant.
