Satan drinks pain. He guzzles suffering, he delights in chaos and torture. They're his vitamins, and he can't survive without them. Neither can he survive in the presence of love, kindness, forgiveness, and Christ.
But yeah...if I spent all of my time studying satan, then I'd leave very little time for learning of Christ and His love for me. I see what you guys are saying, good!
Walk in the light. Have no doubt in Christ and be strong with His word, and then we might be strong enough to step into darkness and not become like it.
