Satan literally means adversary or opposer. 1 Peter 5:8 - ‘Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour.’ I understand this verse thus - Satan or the Adversary is that which is averse to or opposes God/Good and by way of extension godliness/goodness. Again, I think of adversity in a more humanistic and positive way. Speaking from experience, I know that adversity can either make or break a person. I see the proof of that every day. One day, for example, I was watching television, and an interviewer asked an extremely rich man, ‘to what would you attribute your success?’ The man answered - adversity. He said that, rather than adversity tearing him down, it did the opposite. It made him stronger, smarter, hungrier, and shrewder. He became savvier and more creative at solving problems. I have witnessed this myself and have been exposed to many stories of people, from all walks of life, succeeding after overcoming what seemed to be insurmountable odds. My grandparents and parents lived incredibly difficult lives. In a manner of speaking, you might say they were bedeviled. So much adversity. Yet even though tested fiercely, they stuck to their beliefs and principles and became richer in character and godliness for it.
