A lot of churches actually use their resources to help take care of the poor. A lot of them, especially in this country, don't ask if the people are Christian or not because it's more important to be helping people than to convert them.
In Muslim countries, similar acts happen, as charity is one of the pillars of Islam. If you don't give to the poor, they are taught, you are not a true Muslim.
Tammy Faye Messner was one of the first people to bring national attention to the AIDS epidemic of the 80's. She'd bring these people in, junkies and gays, and she'd ask people to help them. Sometimes with prayer, yes, but also to help get them medical care and to try to find a cure. She did this because her understanding of Christianity meant you were supposed to help people, whether or not they were sinners. She might not have approved of their lifestyles, but they needed help, and by God, she was going to help them as best she could.
Have these people also done bad things, often in the name of the same religion? Sure. A lot of the same churches have campaigned against gay marriage. Many Muslims support violence against those they view as heretics. Tammy Faye was, if not directly involved, at least complicit with her husband's mismanagement of Church funds. But they also did some good things for their religions.
