Let us be alert and self-controlled. Arctic polar bears feed on seals. Since seals can be hard to catch, the polar bear resorts to trickery.
Seals usually get their food from a hole in the ice.
If the hole is near shore, the polar bear will take a deep breath, dive under the water, and swim to the unsuspecting seal's fishing hole. The big white bear will then imitate a fish by scratching the undersurface of the ice. When the seal hears this sound, he dives in for supper-only to get caught in the huge, hungry embrace of his predator. The devil uses the same kind of deception to entice us. He disguises the ugliness of sin with something that looks or sounds legitimate and enticing.
