I agree lego, we're born lost, with the Adamic nature. I believe that's scriptural, and that there's no gospel of innocence in the scriptures, no "age of accountability". I believe that's an orthodox invention. Scripturally, all must come through
I personally doubt anyone has an absolutely complete understanding of the Book of Life, as it appears every possible detail isn't filled in for us in the scriptures. There's MUCH MORE to God's PLAN, more than we often see. He's given us many strong promises of the eventual salvation of all when God's righteousness and glory fills the earth. I think it's very possible we don't have each and every detail, but I believe the "bones"/outline is there to be known, and the final outcome revealed, when we're given ears to hear and eyes to see.
Personally, I'm just now seeing some of it myself, and I know there's still MUCH that needs revealed to me.
This is just SOME of the OT. NT to come.
12:1-3 All the families on earth will be blessed..
18:18 all the nations of the earth will be blessed
28:14 all the families of the earth will be blessed
16:22 the God of the spirits of all flesh
8:43 all the people of the earth will come to know and fear you, just as your own people Israel do.
46:10 I will be honored by every nation. I will be honored throughout the world."
65:2 O you who hear prayer, to you shall all flesh come.
86:9 All the nations you made will come and bow before you, Lord; they will praise your holy name.
138:4 O Jehovah, all kings of earth confess Thee, When they have heard the sayings of Thy mouth.
11:9 Nothing will hurt or destroy in all my holy mountain, for as the waters fill the sea, so the earth will be filled with people who know the LORD.
52:10 The LORD will lay bare his holy arm in the sight of all the nations, and all the ends of the earth will see the salvation of our God.
52:15 Kings shall shut their mouths at him: for that which had not been told them shall they see; and that which they had not heard shall they understand.
61:11 or as the earth brings forth its bud, and as the garden causes the things that are sown in it to spring forth; so the Lord Yahweh will cause righteousness and praise to spring forth before all the nations.
65:1 I am sought of them that asked not for me; I am found of them that sought me not: I said, Behold me, behold me, to a nation that was not called by my name.
66:18 it shall come, that I will gather all nations and tongues; and they shall come, and see my glory.
66:23 all flesh shall come to worship before me, declares the LORD.
3:31-32 For the Lord will not cast off for ever: but though he cause grief, yet will he have compassion according to the multitude of his mercies.
NLT- For no one is abandoned by the Lord forever. Though he brings grief, he also shows compassion because of the greatness of his unfailing love.
7:14 And to him was given dominion and glory and a kingdom, that all peoples, nations, and languages should serve him; his dominion is an everlasting dominion, which shall not pass away, and his kingdom one that shall not be destroyed.
7:27 ..the Most High. His kingdom will last forever, and all rulers will serve and obey him."
4:1-5 ..he will teach us his ways,
and we will walk in his paths."
For the LORD's teaching will go out from Zion;
his word will go out from Jerusalem.
3The LORD will mediate between peoples
and will settle disputes between strong nations far away.
They will hammer their swords into plowshares
and their spears into pruning hooks.
Nation will no longer fight against nation,
nor train for war anymore.
4Everyone will live in peace and prosperity,
enjoying their own grapevines and fig trees,
for there will be nothing to fear.
2:14 For the earth shall be filled with the knowledge of the glory of the LORD, as the waters cover the sea
2:7 And I will shake all nations, and the desire of all nations shall come: and I will fill this house with glory, saith the LORD of hosts.
In the NT, there's about 30 scrips I hope to list in the next day or 2. Only part of it is NO MORE CRYING, PAIN, DEATH, TEARS, which IMO = NO ETERNAL TORTURE OR SEPARATION FROM GOD. The outline, outcome, and promises are there. I/we may not know every detail or answer to every possible question, but IMO, those things cannot co-exist.
