If God so loved the world...he wouldn't have made his love and grace conditional.
God would have better proved his grace for humanity if he would have forgiven the first couple their first innocent mistake in the Garden wherein he planted the tree bearing the fruit of their damnation. Being omniscient and the creator of light, darkness, peace and evil and the doer of those things, it was his will, his plan, and part of what the Bible relates it all amounts to; predestination.
God's will, plan that predestined all of creation to unfold by his doing let Satan enter paradise and tempt the woman who had no knowledge of good or evil and thus was absent the ability to choose obedience or disobedience having the knowledge of the penalties or rewards.
And to curse the generations born after to carry the stain of sinner upon them for the sin of Adam and Eve, when the scriptures say elsewhere that the sins of the fathers will not pass unto the sons, is inconsistent with grace, omnibenevolence, and righteousness.
However, prior to all this with Adam and Eve, God banished Satan his adversary, the antithesis of his goodness, to earth where he reigns as Lord. So that humans, born sinners and thus his property at birth being in deficit of grace for being human, have to navigate their way through Satan's domain in order to find Jesus. And then be redeemed from their sinful state.
And all this only happens if someone is exposed to the "good news" that informs them of their fallen damned condition. Otherwise, having never heard the story they're saved due to their ignorance.
Now what sense is that? We're suppose to believe humans are born damned as sinners who need to be redeemed so as to find grace and salvation and be pleasing to God. But yet, if someone doesn't know about that, they're saved for their being ignorant of it.
So really the good news would then be that proselytizing does not exist. Nor do churches. Nor do missionaries. That no one in all the world is made aware of the story of the fall. So that they do not realize their damned condition. And this time those who are ignorant like unto Adam and Eve, will be saved from God because God only puts people on the razors edge between heaven and hell, if they' know the razor exists.
Indeed then ignorance would be bliss.
If you were going to set up law, would you make it unconditional ?
Would you say it is right to have someone murder you or your loved ones?
If unconditional is so wonderful, why do even imperfect nations have laws?
According to Genesis [3 vs 2,3] Eve KNEW, meaning Eve had knowledge. Eve was educated that eating would bring death.
Choice is Not predestined. Adam was told 'you eat you die'. Adam had a choice. Adam was not forced to eat. How many trees on earth?____ Out of all of earth's trees there was only one tree on earth to avoid. If you had a generous neighbor and he said you could come over anytime you wanted and help yourself to all of his many fruit trees except for one tree, would you consider your neighbor as being in the wrong ?
God purposed that earth be populated with descendants of Adam and Eve [us]
-Gen 1 v 28. God did not change his purpose but time has allowed for all of us to be born and think who we would like as sovereign over us.
Father Adam, as our family head, passed down his imperfect nature down to us.
Through no fault of our own we can not stop sinning.
If we could stop sinning we would not die.
We can not resurrect oneself or another so we need someone who can do that for us.
Jesus can and he will. Some to heaven [ Rev. 20 v 6], and the majority of mankind resurrected back to life on earth during Jesus 1000-yr reign over earth. [John 3 v 13]
'Death' [No post-mortem penalties] is the wage or price tag that sin pays.
-Romans 6 vs 23,7
So, since the majority of mankind did not have the opportunity to learn about Jesus, they will have that opportunity when resurrected on earth during Jesus millennial reign over earth, or earthly subjects of God's kingdom in the rulership of Christ Jesus.
-Psalm 72 vs 8, 12-14
The 'times of ignorance' is now past. - Acts 17 vs 30,31
God desires all to repent.- 2nd Peter 3 v 9 B.
That is why the 'good news of God's kingdom' is now being proclaimed on an international scale today. - Matthew 24 v 14; Acts 1 v 8
Please notice verse 14 says as a witness 'to the nations' . Not every individual.
New people are being born every day. That was true in Noah's day. God knew the point when the people became beyond reform or beyond repentance.
Modern technology had even made possible rapid Bible translation into many foreign languages possible so that earth's people world wide have Scripture in their mother tongue or native language.
'Razor's edge between heaven and hell' is a religious-myth hell teaching often taught as Scripture. Just as God resurrected Jesus out of hell [ see Acts 2 vs 31,32], some others like Jesus are resurrected to heaven [ Rev. 20 v 6; 5 vs 9,10] out of hell.
That is because the temporary biblical hell [sheol] is just the common grave of mankind. The common grave where the dead sleep the deep sleep of death until resurrected either to heaven for some, or resurrected back to life on a paradisaic earth during Jesus' coming 1000-year reign over earth.
The English words 'hell and hellfire' are from the Hebrew word sheol and the Greek word hades [haides] and Gehenna. Gehenna was just a garbage pit outside of Jerusalem where things were 'destroyed' Not kept burning forever, so Gehenna is a fitting symbol or way of saying: destruction Not eternal burning.
The wicked are to be destroyed forever. -Psalm 92 v 7; 2nd Thess 1 v 9
Jesus taught the dead are in a sleep-like state [John 11 vs 11-14]
That teaching is in harmony with the Hebrew OT Scriptures.
[Ecclesiastes 9 vs 5,10; Psalms: 6v5; 13v3; 115v17; 146v4; Daniel 12 vs 2,13]
So, during Jesus messianic 1000-year reign over earth Satan will be abyssed.
According to Rev. [20 vs 13,14] everyone in the temporary Bible's hell [grave] will be 'delivered up' meaning resurrected out of hell which is just the temporary common grave where the dead sleep the deep sleep of death until resurrected out of hell. Then please notice that it is 'emptied-out hell' that is cast vacant into a symbolic 'second death'.
'Second death' is the condition that Satan will end up in according to Rev. 21 v 8.
Jesus destroys Satan [ Hebrews 2 v 14 B ], so 'second death' if a fitting symbol for destruction or being destroyed forever.-Psalm 92 v 7
