Church members who are selfish

Why do some people come to church, talk about sharing & think that money is everything? Why can't u carry home someone out of your way? Why can't u help someone do some menial tasks that are below you? aren't we calle dto do things like this? Or only the offering plate matters? Just my opinion but I think that most christians are selfish. Still too carnal. But then, Who am I to talk? I am one too and my carnal desires aren't better than theirs. So shall we all pray for each other? Work on the giving of non-monetary things though. Make God proud.
