I think we tend to judge God by our limited human understanding, after all we are made in Gods 'image', we are not equals or even clones, just copies of the original, and like all copies marginally different, i.e. we have a tendency to degrade the copy with each new version made.
It would be good if we improved the copy each time we generated a new one, and in the theory of evolution that is the objective, however evidence seems to suggest it's not the fact.
Instead of becoming more civilized and humane, we have invented better ways to kill more effectively, sin more copiously and rebel without conscience.
Hell..... mostly misinterpreted by the dark ages Catholics to ensure control over a simplified peasantry, but biblicly secure in scripture.
God MUST create a place where He will undertake not to exercise His authority, for and over those who reject His authority (rebels) and.... in that place He will choose to NEVER again intervene in the affairs of those who choose to be there by rejecting Him.
Scripture tells me that it will contain:.... the cowardly, the unbelieving, the vile, the murderers, the sexually immoral, those who practice magic arts, the idolaters and all liars.... so that's the company those who reject God choose to keep for eternity.
But it's a choice, and it's widely publicized and possibly the ONLY defense would be to be able to honestly state you never KNEW that this was the choice you were making.
We may not think that's fair, that God, having told us plainly what the consequences of our words, deeds, actions, thoughts and choices are, and how they could affect us,.......we may think God is being unreasonable when He creates a special 'null and void' space secured from His eternity for eternity.
But I cannot agree with you if you feel that, for when one has been clearly told of the eternal reactions to our temporal actions, and when God has tried specifically hard to make us aware of our choices and consequences, and when we have deliberately chosen to rebel and reject His love and protection under His authority..... we are 100% to blame for what happens when we end this 'soul school' and return home to collect our results upon death.
Nobody forces separation from God on us (though the enemy tries to deceive us into choosing it) it is always OUR personal choice, it is always OUR personal responsibility to face the consequences of our choices.
Think on this, and you will see it's the truth.
