Christians hear a lot of sermons about putting on the whole armor of God, but not so many about how to actually fight the devil. James talks about resisting the devil, but how do we do that? Every time we choose good over evil, right over wrong, to help and not to turn away - we punch the devil in the face and stick a knife in his belly. Words of encouragement, prayer, sharing the gospel and acts of kindness all serve to put the devil on the run.
