I am not sure where you ever got the idea that man does not go to hell because he is a sinner. That is simply false. Second The justice is you do not deserve a chance to repent and go to heaven any more then anyone else. Going to heaven is not about justice or your right, or what is right, it is about mercy which we do not deserve. We do not even deserve a chance to hear the gospel much less accept it.
As to your last question, even though I do not claim to be a Calvinist, I have heard several testimonies of such instances and the "jungle boy", as you call them, leaves the jungle and goes to a place where they can hear the gospel when no one has went to them.
I agree with you, and let me explain my statement.
Yes, we all deserve to go to hell because we are sinners. Our sins are the reason we need to believe and repent.
But, the only way we will actually go to hell is if we refuse to believe and repent.
Jesus already paid the price for every sin that man will ever commit. Again, every sin a man can ever commit is already paid for by the blood of Christ. The only sin left unforgiven is the sin of unbelief. If we refuse the gift Jesus paid for on the cross then we are lost and destined for hell.
The bottom line is that the only sin that will send us to hell is failing to believe and repent.
I guess I see it from the oppisite direction of Calvinists. They believe that God gives only a few of us the ability to repent, so to them it is the actual physical sins that condemns one to hell, and God chooses whom He will forgive and who He won't.
I see it as we all have the ability to repent, but most of us don't. It is that refusal to repent that condemns one to hell. I believe that God will forgive and save anyone that earnestly seeks Him.
I would like to add one more thing. I believe that our lost state is due to the nature of sin that we are born with, and that our actual physical sins are just the result of that state. It is the nature of sin within us that condemns us before we ever actually commit a physical sin.
We all have that sin nature, but it is the ones that refuse to admit it, believe and repent that will be condemned to hell.
I honestly believe that even Charles Manson could believe and repent and go to heaven if he would seek God. I believe that if he asked God for help that God would not deny him that help, and that God would send the HS to minister to him. If he doesn't, he will go to hell for his unbelief, not for his actual physical sins.
Jesus paid the price for our physical sins, but refusing to accept that is the sin that is not forgiven and condemns us to hell.
