There are few experiences that equal biting into a crisp, flavorful apple,. There is nothing like that first bite of a first ripe apple of the summer. Sweetest fills you mouth, and juices run down you chin.
But few experiences are worse than finding half a worm in the remaining portion. Sin is like the worm, which is really codling moth larva. On the outside of the apple you might see a small hole; a little blemish. But when you open the apple up it is ruined.
Sin will destroy you life from the inside out just like the codling moth larva, or apple worm. You might be able to hide the blemish from the rest of the world, but you are ruined on the inside just the same.
