I've been bothered about time generally and our tripartite division of time into past, present, and future. I think I know what the past is, and I think I know what future is, but I'm really not comfortable with the notion of present.
Optimistic people generally feel that good things will last a long time and will have a beneficial effect on everything they do. And they think that bad things are isolated: They won't last too long and won't affect other parts of life.
In human history, we are going from knowledge to omniscience, from potence to omnipotence, from ethics and religion to righteousness. So, in my view, God comes at the end of this long process. This may not happen in our lifetimes or even in the lifetime of our species.
