Often times, when someone is admonished for a particular behavior, they will say something like this: “Show me in the Bible where I can’t do this! I want a chapter and verse!”
There are (rare!) times when this is an appropriate thing to say, because some folks want to create rules where the Bible has not.
But most of the time, folks who say this are not being faithful to the text of Scripture. They are trying to find an excuse for what they know is bad behavior. They need to repent not only of the behavior, but of their stubborn attitude.
