I've thought about this for a long time, especially after losing my mother over the course of a decade. It was a long, cruel ending of a selfless person.
I have now concluded that the basic principles that I was taught (Catholic) of an all-loving, all knowing, and all powerful God cannot be true. Two out of three may be, not all three. Probably none. So, if there is a God, I think that God must have bigger fish to fry.
We are given the tools to affect are future and would be wise to do so in the best way we know how. That obviously means we have to take responsibility for our own welfare, but realize that we are all in the same boat. Tremendous support is there, given this collective predicament.
