Actually, the God revealed in the Bible is exceedingly benevolent, but not omnibenevolent.
If God is omnipotent and omnibenevolent the Fall could never have happened. A truly omnibenevolent God would never allow anyone to die, in any sense of the word, much less for sin and its result to corrupt the perfect world.
That is your personal way of defining “omnibenevolent”.
Is being benevolent glorious, praise worthy, honorable, righteous, holy and God like?
What could possibly keep God from being “omnibenevolent”?
All that I see throughout history, in scripture and in this world displaces an omnibenevolent God, but you do have to keep the objective in mind.
I see God allowing and doing everything to help willing individuals in their fulfillment of their earthly objective.
God’s sack becomes for the sack of others.
Has God given man a mission statement? (this is always good to have)
You can take any command in scripture and have Biblical support for calling that command “Man’s Objective” and have Biblical support for saying that, but there are two overriding commands all other commands are bases on.
Would “Loving God and secondly others with all our heart, soul, mind, and energy” be our Mission statement?
God is Love, but how do we define this Love and measure this Love?
This Godly type Love is defined by Jesus’ words and deeds (you can also use 1 Cor 13 and 1 John 4), so what is that?
Can we measure the “love” one being has for another being by the amount the first being is willing to unselfishly sacrifice for the other being?
Is God this ultimate Lover? Would that “Love” compel even God to make beings that could Love like He Loves (this “Love of God” is totally unselfish [a measure of pure Love] and thus is not for God’s sake at all, but is totally for the sake of others)?
So if God is not doing anything for His own sake and everything for the sake of others, would He be expecting or needing anything from man or would God just be trying to give the greatest gift He could give to man?
The reason this “Love” is the most powerful force in all universes is because it compels even God. So to have this Love would make us like God Himself, so why does God not just make us with this Love and place us in heaven?
Are there something God just cannot do: like make another Christ, since Christ was never made but always existed?
Could God place this Godly type Love in a person at his/her creation (an instinctive love) or would an instinctive love be like a robotic love and not like God’s Love?
Could God just force His Love on man against the “will” of man or would that be like a shotgun wedding with God holding the shotgun?
What does man need that he does not have instinctively in order for man to fulfill this Mission?
Man’s objective seems to be to obtain and grow this Godly type Love to fulfill the mission (statement) of Love God and secondly others with all our heart, soul, mind, and energy.
Our “objective” while here on earth is to just accept God’s gift as it was given as pure charity.
God is not trying to get you to do something, but is trying to give you something.
The problem is not sin (unforgiven sin is a huge problem), because God will forgive our sins which helps us to Love (…he that is forgiven much will Love much….) God hates sin, but does allow it so we can more easily accept His Love (in the form of forgiveness the easiest way for us to accept His charity). The problem is always our fulfilling our objective.
You say: “If God is omnipotent and omnibenevolent the Fall could never have happened.”
But you are missing one of the great lessons in the Adam and Eve story. The Garden is a lousy (impossible) place for humans to fulfill their earthly objective and we can thank Adam and Eve for going through that example and providing us and them with that knowledge.
Sin is not only inevitable, but it unfortunately is necessary for humans.
The easiest way for humans to accept God’s charity (Love) is out of a huge need and that need is the relief from the burden of hurting others in the past (sin). By accepting God’s forgiveness we accept God’s Love (mercy/grace/charity) and thus we will Love much since Jesus has taught us (we also see this in our own lives) “…he that is forgiven much will Love much…” Luke 7: 36-50.
You said: A truly omnibenevolent God would never allow anyone to die, in any sense of the word, much less for sin and its result to corrupt the perfect world.
This world is “very good”, but not “perfect” like heaven is perfect and does not have the same purpose as heaven. This messed up world is actually the very best place for willing individuals to fulfill their earthly objective.
Death is not “bad” in and of itself, but the way good people go home and the way bad people quit doing bad stuff.
It is truly tragic and unfortunate that Christ had to be tortured, humiliated and murdered in order to help willing humans in their fulfilling of their objective, but God is willing to make huge sacrifices to help willing individuals. It is also very sad other humans who had the opportunity to fulfill their primary earthly objective continued to refuse God’s charity to the point they would never of their own free will accepted God’s charity. These God Loved individuals will thus go to their death and destruction as a help to some other humans who have not refused God’s help to the point of never accepting His help.
