To work towards a goal in which to be received in a place where ultimate salvation lies, heaven. Gosh, that a pretty story isn't it. It's to bad that in saving your soul you are only thinking of your own ass and none other. At least we can decipher a justification in having faith in religion as opposed to science. The answers that one looks for in science are to explain things where as in religion it is to make oneself feel good about himself and the world around him.
Religion has answers and searches for the reasons that support their answers.
Yes, yes science has been acused of supplying answers then finding reasons, but that is bad science.
