The Christian narrative is that in the beginning was God and he created this whole universe and existence. If this is true then this all powerful God is responsible for the great horror,suffering, and evil in the world. The reply is that God wanted creatures to have free will but this is questionable because at best existence for humans is a mix of deterministic factors as well as their will. So that is not a very fair system. And is there really a clear choice? There are other claims about this God and the Christian narrative must be taken on faith. So the choice is really more like chance.
Also who is responsible for Satan if not God? And this God apparently gave Satan free will so it is not just for humans. Also do humans have free will in heaven? And if they do then it is possible to create a world where humans can live in perfect peace and have free will. So why all the prelude of death, disease, confusion and hell from a perfect Creator? The horrible truth is that for the Christian narrative to be consistent then there is no security in heaven either! In fact one verse in the Book of Revelation talks about a rebellion a thousand years after the return of Jesus. This is the best of all possible worlds? Some new angel may rebel like Lucifer or another Adam and Eve will rebel with their "free will" and we can start the whole confusing mess all over again. Even as a Christian one cannot be secure in future justice and peace because Satan and Sin according to the narrative started from divine perfection and creation!
If God is all good and all powerful it could have created a world where it started and ended with eternal bliss. Boredom not compassion would be the reason for creating a world such as ours. Does not God have free will? Is not God responsible for all things including evil and the suffering in it?
Question with boldness even the existence of a God; because, if there be one, he must more approve of the homage of reason, than that of blind-folded fear.Thomas Jefferson
The tragic history of human civilization and its many competing narratives of meaning...
Sophocles long ago
Heard it on the Ægæan, and it brought
Into his mind the turbid ebb and flow
Of human misery; we
Find also in the sound a thought,
Hearing it by this distant northern sea.
The Sea of Faith
Was once, too, at the full, and round earth’s shore
Lay like the folds of a bright girdle furl’d.
But now I only hear
Its melancholy, long, withdrawing roar,
Retreating, to the breath
Of the night-wind, down the vast edges drear
And naked shingles of the world.
Ah, love, let us be true
To one another! for the world, which seems
To lie before us like a land of dreams,
So various, so beautiful, so new,
Hath really neither joy, nor love, nor light,
Nor certitude, nor peace, nor help for pain;
And we are here as on a darkling plain
Swept with confused alarms of struggle and flight,
Where ignorant armies clash by night.
Matthew Arnold Poem 1867
