Sin is like an itch. You know you ought not scratch it, but sometimes, you just can’t help it. When you do, scratching feels so good. But the more you scratch, the more you itch — until one day, you look forward to the itch because you like the scratch. At that time, it becomes more about the scratch and less about the itch. The itch has become a part of you. You’ve scratched so much that you’ve become the itch.
