It is important to realize that the demonic forces are servants, not opponents, of Oneness. This means that we must respect that they are highly skilled in what they do — being tricky, devious, and persuasive. Each time we make a resolution, and then find ourselves breaking our resolve, we can recognize the power of these opponents. We need patience, wisdom, tenacity, self-discipline, self-compassion, and strong conviction to contend with these powers in a loving way, without rancor, anger, or hatred. Just as some angels can be destructive, avenging, and not-so-pleasant, so too can some "demons"; be useful, kind, generous, and helpful.
