It depends on what you mean by "a reward." A sense of personal satisfaction in having done a good deed is a reward, but it's not a tawdry, mercenary one: it is simply the natural culmination of a good deed, rightly earned.
I'm not sure that it makes sense, WT, when you say that if one is doing something "because it's part of his religion," that therefore one is not doing it "on your own." You choose your religion--and choose to adhere to it--"on your own." And all that stems from it is part of that choice. You might as well say you're not doing good when you do anything good, because you always do so in some broader moral framework that tells you it's better to do it than to not. Ergo, according to this logic, good deeds do not exist.
