Self-examination and Repentance
There are people who, entrenched in their church’s brand of teachings that justification comes solely through Christ’s sacrifice. Thus, they convinced themselves that if they practice self-examination and repentance, some of their own darkness might spring up ruining their faith and divert their salvation from its sole focus.
Hence, they are like those who experience pain in their bodies but will not have them examined for fear of what they may find. And they remain home bound while hoping that the pain may just go away.
