In Evil and the Satan Hypothesis mwillet says:
Doesn’t it make sense just to live a good life and avoid doing anything you will later be ashamed of? That’s not to presume there is a life after death, just a working hypothesis that there is probably going to be a day after today and most people want to feel comfortable in their own skin.
Don’t bother asking yourself what would Jesus do because unless you want to be the judicially murdered virgin penniless beggar leader of a new cult it isn’t likely to be a useful answer, ask yourself what the future you would have wanted yourself to have done.
