This quote explains how an intelligent person would approach the idea of a “god” or gods:
Live a good life. If there are gods and they are just, then they will not care how devout you have been, but will welcome you based on the virtues you have lived by. If there are gods, but unjust, then you should not want to worship them. If there are no gods, then you will be gone, but will have lived a noble life that will live on in the memories of your loved ones. [ref]
The only approach is to live a good life. Since there is no evidence for a god or gods, an intelligent person assumes that they do not exist. Living a good life is the right path no matter what.
What’s funny is that Christians believe in an unjust God – the worst-case-scenario of the three options presented. They worship a god who they know to be unworthy of worship.
