Playwright Anton Chekov had a rule in writing that if the audience sees a gun in the first scene, it has to go off in the second or third scene. It has to be used. This rule is known as Chekov’s Gun. We can watch a movie and recognize that some object or piece of information, if introduced at the beginning of a story, will have to come into play later on.
“Remove everything that has no relevance to the story. If you say in the first chapter that there is a rifle hanging on the wall, in the second or third chapter it absolutely must go off. If it’s not going to be fired, it shouldn’t be hanging there.”
When you dedicate yourself to a consistent devotional life and dive into scripture daily, you will be surprised to find how often what you read will apply to situations you find yourself in that week. It’s like Chekov’s gun. You’ll read the Word in chapter one and find yourself needing that exact truth in chapter three.
