I have posted several studies, books, and surveys, that all corroborate what i'm saying. You cannot simply write them off because you dislike them. If they are bullshit and you are right, please do post some conflicting evidence and I will happily look at it and change my view accordingly. Until then I won't walk around with blinkers on like some people who for some reason don't like the truth. I will see that when there is an emergency it is Christians who are the first on the ground and the last out, regardless of if that nation is Christian (look at Sudan, they weren't allowed to talk about Christianity to locals by law. They were also allowed one bible, and weren't allowed to hold services of any kind. The same was true in Pakistan recently too). I will see that most homeless shelters and soup kitchens in this country are Christian run, and Christian funded. I am not saying Christians are better people, but if they give more to charity because of Christianity and this is saving millions of lives then Christianity cannot be the evil thing many want to paint it. I regularly hear people go on about the Spanish Inquisition, which no right minded Christian will tell you was right, which killed an estimated 1300 people. But I don't hear them mention that it was Christians helping out in Africa before it was cool and Bono got on the case.
The whole point of Christianity - yes CHRISTianity; Is that Christians should seek to become as much like Jesus as possible. Jesus was fundamentally charitable and helping. Christians believe this makes God happier, not that they should or will get anything extra in the afterlife for it. Nor will they not go to heaven if they don't partake one iota in it. Have you ever actually been to a church before? I have been to hundreds of services and not once have I ever heard them say charity was mandatory, and that if you don't do it you will go to hell. They don't pass around a collection plate saying dig deep or satan's gonna get on your case.
With regard to the person in the wheel chair analogy. Perhaps the person who could help them up the stairs should just sit around and wait for God to do it, regardless of how simple and easy it would be for them to help?
