Man has 2 common problems with God: the one is that there is evil in the world; the other is that free will is limited. The one, he is charging that the world is too evil; the other is that it is not evil enough.
I'm convinced that most men don't know what they believe, rather, they only know what they wish to believe. How many people blame God for man's atrocities, but wouldn't dream of imprisoning a mother for her son's crime?
I would rather my descendants have greater abilities and a greater knowledge of the love of Christ than I do, much like standing on one's shoulders in order to get a clearer view of the valley.
