They are all appealing to their own good works.
That’s one of the challenges. As a Christian you do need to examine yourself and be “as good as you can be”, but not to be saved because your salvation is the gift of God. But when you think you are doing pretty good, or when you think your salvation is at risk because your works of late are not up to snuff, you are missing the point in both cases. But we all do it to one degree or another. At least, I do.
