A false mission

It seems that some people's mission in life is to "set the other guy straight." Some even do this in the name of Christianity, which is totally missing the point. My sister's landlord is harasssing her and has her intimidated into "repaying" some gravel that he had previously told her to take from a pile he had dumped on a vacant lot in the trailer park where she lives. Since she suffers severe back pain and has arthritis, she had her muscular 35-year-old son-in-law fill the wheelbarrow and take the gravel for her, and an elderly neighbour felt "frightened" by him doing this. (I told my sister this elderly man is likely going paranoid in his old age, as is not unusual). Anyway her landlord gave her a note saying he was charging her $150 for the gravel she "stole" from him. Now my sister is a widow living on a pension and $150 to her is a lot of money. I told her to quote the scriptures from the Bible, "This is true religion to visit the widows and orphans "in their distress" and to keep oneself unspotted from the world." I believe the words "in their distress" are very true. My sister is in both categories having been an orphan (at least as far has her fathers go) since the age of 16. She never knew her own dad as he died when she was just 11 months old. Her adoptive dad was good to her, but he was killed when she was 16 - too soon to lose one's father. A teenage girl especially needs a father to guide her life and our adoptive dad would have done that, he was a good parent. Anyway, I digress, but I can't get over how some people think that it is their Christian "duty" to preach to others and not their duty to help them, especially the widows and orphans. (My sister's husband passed away just a few months ago).
