Satan was/is cherubim I don’t know whether or not they are flesh and blood or if they can “take on” other forms. My gut feeling is that evil is more spirit than substance. I don’t know how well that fits into traditional Christian beliefs.
Depression has at least some base in chemistry, so I can’t say for a fact that is what I mean by being consumed. It may also be that the chemical changes are brought on by the psychological stresses of being, or rather being made to feel, separated from God. Ones spirit can be consumed by a variety of “things”…jealousy, greed, lust, etc. All are not productive by any measure and can be considered evil, if evil is the absence of good.
I need to say that I am in no way a Biblical scholar, theologian or even on the right path in life. I hold rather unusual beliefs, probably unique is a better word. In fact I know more about what I don’t believe than what I believe in.
