Reflections of a Princess

I thought this was a good analogy for sin:

Nancy Leigh DeMoss: When the Romeros got Sally as a family pet, she was one foot long. Eight years later, Sally had grown to eleven and a half feet. She weighed eighty pounds. Sally, the family pet, was a Burmese python. On July 20, 1993, she attacked fifteen-year-old Derek, strangling the teenager until he suffocated to death. The creature that had seemed so harmless was exposed as a deadly beast.
It reminds me of sin. It seems so harmless at first. It may play with us, sleep with us, or amuse us. But its nature never changes. The book of James tells us that “sin, when it is fully grown, brings forth death.”
Do you have some pet sin in your life? The best way to protect yourself is to confess it to God and turn from it. Remember: Sin will always rise up and devour those who befriend it.
