Again, one can hold a belief in God.
One can't say with certainty that "God loves us so much that he wants the best for us." That's an assumption, at core, just like you might take an algebraic equation and say, "Assume that x=3."
That's what a lot of this is.
One person says x=3.
Another says x=7.
Another might say that z = x-y.
It's nice to speculate those different things and see what patterns we can find if we start with particular assumptions.
But in the end it's all based on the assumptions.
There are no answers, only choices.
