I have some trouble to see how faith and trust fit into this conversation.

I always had a strong knowing that I am guided, and all will just work out in some way. Like being part of a benevolent universe. 

So if we are life living, and there is no me, then there is also no me some universe may care about. Life moves towards thriving, but as I see it, not in a particular way, when we look at biology, like plants and animals. It seems the one particular tube is not important in the big picture. 

So now what, are those body-mind systems just randomly held in life or not, depneding if it serves the thriving?  If yes, how can the human psychology get along with that?

Or am I misunderstanding everything?
