What if I live as if God exists for different reasons?
I have no way trust any religion, and the only theological tool I've got left is my moral and ethical perception.

Now, if there is a God and there is an actual divine afterlife, all the suffering I've witnessed so far is meaningless, and I'll be able to accept it. If this is true, acting in a ethical manner is probably what he meant me to do, so there's nothing wrong with it.
If there is no God, at worse I'll have probably helped and improved the lives of who is dear to me, and maybe even the society that surrounds me. The thought of doing this, lf improving the world, gives me enough pleasure for me to genuinely justify my ethical and moral approach, and in fact doing otherwise would actually cause me more harm than anything, especially psychologically. If there is no God of course my ethical sense becomes a mere istinct built in me and doctored by society and culture, yet in a nihilistic framework this would not matter to me as long as I can impose skepticism on said perception of ethics and morals.

I'd say it is a clueless approach, since I've never confronted it with actual philosophy (I mainly read literature), yet I can't see many faults in it. Would you guys consider it as bad as Peterson's one?
