Mishap I think it's a mistake to assume that Christians who do good things only do so for other motives or that only Christians are so motivated. Undoubtedly, many people do good for other or additional reasons - for example, it makes them feel good about themselves or they want to look good and I suppose the same is true of some Christians, hope of heaven, fear of hell or the desire to convert. Not every one of us, though, surely? If there is such a thing as pure altruism, Christianity promotes that as much as any other belief system. I include personal philosophies in the last term.
