A young girl had a pet boa constrictor. She loved it and would let it get out of the cage. It was like a member of the family. She let it slither around - loved it, cared for it, fed it. Eventually she began to let it sleep in her bed with her like a friend. It would stretch out along her back and cuddle with her. She thought it was very sweet. Then, after a while, she noticed that the snake had quit eating. No more rats or mice. So she took it to the vet. He asked if the snake had experienced any trauma or sudden changes to its life or diet. She said no but left out the part about it sleeping in the bed with her because she didn't want to sound weird. He said if it continued to be a problem, to bring it back. So she took it home and nothing changed. She grew more concerned and began to freak out. She went back to the vet and he asked her if she was sure nothing significant had changed. She finally admitted that the snake was sleeping with her, and shared how great it was - it stretched out and snuggled up next to her. The vet immediately reacted and told her to stop. He corrected her that the snake had not been cuddling with her. In fact, the boa constrictor was measuring her. The snake was starving itself so it could eat her. He told her that it is not a pet - it wants to devour you.
And sin and temptation are the same way. You don't own it, it owns you.
