Stay alert! Watch out for your great enemy, the devil. He prowls around like a roaring lion, looking for someone to devour. 
—1 Peter 5:8

You have probably seen it on television at one time or another: some lions are hanging out, soaking in the rays, when along come the antelope. You can almost read the lions' thoughts as they size them up: Let's see, which one are we going to eat today? There is usually that lone antelope lagging behind all the rest by about 20 feet or so. That one looks like lion lunch. So the next thing you see is a lion covering an amazing amount of ground in a matter of seconds. And once the big cat sinks his claws into his prey and drags it down, you know it is all over for that antelope.
