warfare

Dictionary of Biblical Words:

The Christian conflict the believer has to maintain against Satan according to Eph. 6 Observe the Christian is not called upon to war against the world, he is crucified to it, neither is he to war against his own evil nature, but to reckon it dead (Rom. 6) His warfare is defensive and aggressive; he holds fast what he has against all the assaults of the enemy, and attacks the powers of wickedness and darkness wherever he finds them.
