That's fairly common in twi and in ex-twi communities, though. You might hear criticisms of people who volunteer and help others, but exhortations to help them are not nearly as common. They exist, but not in every group, and not all the time. The rank-and-file may already have more impressive track records on that sort of thing.
When I was in college, I was in a service organization, and logged some 40 hours of community service, etc per semester (sometimes more.) After a few years of me doing that, the ex-twi group at the time discussed, at the leadership level, the idea that it's good to do that sort of thing. Shocking for all the twi-trained people. For me, the mention from a local leader that this sort of thing was good was in the "and the water was actually wet?" category. I agreed, mentioned I had a few YEARS of experience with that sort of thing, and offered to advise them and pass information if he needed any. He was polite, but his face was easy to read. You'd think I was offering to perform a necessary surgery for him in a garage or something. The idea that I might have actually gotten experience and training they lacked and needed, and got it from a secular source, that was either shocking, repugnant, or shockingly repugnant.
