The premise of the question is the erroneous assumption that man creates and manufactures his own reality according to his needs and wants. This kind of thinking elevates humanity to the supreme form of life and intellect. Eventually, if pressed through force of reason this person would have to admit that humanity is demonstrably weak and prone to error and is woefully inadequate at thinking itself out of its troubles. Such a person seeing too many uncontrollable external factors that shape our lives outside of our control would ultimately have to invent some other false God; perhaps some superior form of humanoid alien that spontaneously emerged out of the aether to ascend to a divine status. :rolleyes:
The person who asks this question is light years away from wanting to really know the truth and just looking for an excuse to be lazy and not confront the overwhelming natural evidence that God reveals himself through His works. Such a person is not sincere in their own beliefs but is searching for some other rationale reason why we are all here.
If there was no God then there would be no grace, no creation, nothing but a utterly dark, empty, silent and cold void that would be impenetrable to thought for us to even imagine. If life could exist, and it can’t it would be pure animal survival with no capacity for love at all - just co-dependency relationships to stay alive. But a Godless and empty universe would be so foreign a concept that if our minds could reflect accurately upon even a small dimension of “nothingness” we would be driven mad. Without God, there would be no opportunities even for “chance” events or any change. All that would exist is a void of hopelessness. And that sounds like an eternal hell to me. “Abandon Hope all ye who (imagine to) enter here.”
Without God, an infinitely worse and unbounded Hell than now exists to serve God’s Justice and His Mercy would spontaneously create itself from nothingness out of a universal necessity to despair, lament and curse itself. It would make itself god for no other reason than to hate and despise itself for not manifesting life and purpose.
It is Evil that needs something other than itself to loath to take its mind of of the fact it is eternally alone with its own company. Thus the godless soul needs God to blame and account for its hopeless and unchanging existence. There are no atheist in Hell - only true believers who hate that they found the only God they imagined existed - themselves.
God needs only God - everything else is an expression of God’s love for Himself. All we have to do is stay the course in God’s grace and be born as God’s children. Those wishing to exist without God are free to abort themselves at anytime and take care of themselves without any of God’s help in Hell.
