Folk wisdom used to say that when you boil you a frog, you don’t throw it directly into the boiling water. Instead, you throw it into room-temperature water and gradually turn the temperature up. Doing this allows the frog to get comfortable to the point where it doesn’t even realize that it’s being boiled. While later science discovered this wasn’t the case, it still makes a helpful image for Christian in relationship to cultural idolatry. A great example is found in Numbers 25.
