I take an interest in subjects like God and any form of deity simply because they are not that easy to discern and will necessarily take a long time to figure out.
One of the more telling aspect of the nature of God is the afterlife. Accept the notion that there is a creator of existence but then also consider the prospects of said creator condemning its creations to either live in perpetual joy or agony is childish. However, that promise remains central to what believers do or do not as it were.
Central to the understanding of the afterlife is the idea of eternity. Eternity for a creator is not a problem since there are many ways to achieve the same end in some fashion. The more impressive bit of it is that as a creator, it is entirely possible to hide your eternity in your creations.
Every single person who believes that there is a creator, keeps the creator alive and well for as long as the species continue to exist. That said, don’t discount the idea that evolution does not serve the same function of creating ever more rationally capable beings in the process. That is eternity simple and logical.
The next more interesting question is why individuals so created attach so much importance into something that is fundamentally against their very nature of existing. It boils down to this, do you want to fight God and if your answer is yes then it would be interesting to hear more about how you are progressing in your effort. However, also giving yourself completely over to God is somewhat unworthy of you as you have been created.
To put it more simply, the kinds of things that you will do to offend God may ultimately be something that you are doing to please yourself and as such God has very little to do with it. Yes, if you are displeasing too many people – there is all chance that your objective intention can and will be defeated; it is not an act of the devil. However, it does mean that there people who are opposing your intentions. I do allow myself to see what other people think of me for just that kind of an outcome.
