All of us battle sin, but the problem is even greater than that. God has an enemy, Satan, who’s working not only against God but against us to help sin and evil triumph. This may seem like a strange topic as we head into the Christmas season, but if we don’t understand this enemy and his purposes, we won’t fully understand what Christmas is really about. War has broken out in Heaven and spilled down onto earth, and we’re caught in the middle of it. But Christmas is how God begins to strike back and retake all that is rightfully His, as we’ll see this morning!
