The first premise is false because omnipotence doesn’t entail inconsistency. Since only God is perfect in every respect it is inevitable that everything created by God is imperfect in some respect, i.e. it has limitations and drawbacks. Therefore the argument is invalid…
Unsurprisingly heaven is in a different category from earth. There is no moral or natural evil because it is a spiritual realm in which everyone is united to God.
And there is no reason why logic constrains an all-powerful, all-knowing and all-loving God to only being able to create a world in which a child dies of diarrhea every minute of every day.
God is not constrained but He is consistent. It would defeat the purpose of creating the laws of nature which are essential for physical life if He constantly suspended them simply because of disease and starvation that are largely caused by human greed, indifference and selfishness. We do not know to what extent God intervenes to prevent and alleviate suffering and death but we can be sure He does His utmost to do so unless we are hardened cynics and sceptics like Schopenhauer who think this is the worst of all possible worlds. Obviously there are disasters such as epidemics, droughts, earthquakes, hurricanes, tsunamis, and avalanches but how could they all be prevented without depriving us of our freedom to choose what to believe and how to live? If we object to Big Brother observing all our activity how much more constrained would we be if we knew for certain every single thought, feeling and temptation is known to God…
And logically, even in this world, an all-powerful God could act to stop such suffering.
How do you
know God never or even rarely prevents or mitigates pain and misery? Do you have any evidence? If so produce it.
Or don’t you believe in miracles?
It sounds as if you are the one who doesn’t believe in miracles. Otherwise you wouldn’t have emphasised so wholeheartedly that natural evil is an overwhelming objection to the existence of a loving God beyond all possible doubt. It seems incompatible with being a Christian - unless you agree with Luther that reason is a whore and subscribe to the dictum “Credo quia absurdum”…
