In an obscured version of Christianity, it appears as though you have to do particular things that are not actually the gospel in order to follow Christ, because all the Christians you know do them.
It could be as simple as a change in dress or hairstyle or musical tastes; or it could be bigger issues like political bent or a particular worldview. But, it could be a hundred other things—I just gave two examples. Ultimately, seeing these things as the gospel is actually a false gospel.
