If you were paying attention during physics class in high school, you’ll know that there are certain laws that the natural world abides by.

The Law of Gravity, for instance. Legend has it that this principle was discovered by a young Isaac Newton when he was hit on the head by an apple which fell from the tree he was sitting under.

Or the Law of Inertia, which states that an object at rest or in motion will continue in that state unless acted upon by an external force. So when I’m sitting in my easy chair and don’t want to get up to do any housework, I’m not being lazy. I’m simply obeying the law of inertia.

I recently heard a wag rephrase Newton’s Third Law of Motion (“For every action there is an equal and opposite reaction”). He dubbed it the Law of Emotion: for every male action there is a female overreaction!

Then there’s the Law of Conservation of Energy, which says that energy can’t be created or destroyed, but can be altered from one form to another. For instance, our bodies transform the chemical energy in food into kinetic energy to help us move around.

I think sin has a principle attached to it which is similar to the Law of Conservation of Energy.

Sin can’t just disappear. It has to be dealt with in some way.

But it can be transformed.

As author Dorothy Sayers said, “There is only one real law—the law of the universe. It may be fulfilled either by way of judgement or by the way of grace, but it must be fulfilled one way or the other.”
