The only scripture that people point out is Hebrews that it is appointed for man to die once then the judgment, the lense that western church has used says judgement and punishment are the same, heaven or hell, but the tradition I follow is that of many of the early church, that 1 Cor 15:28 that God will be all in all- that is Gods telos and you work backwards from that telos, the only conclusion is that God pursues us, our true self, not just when we are in our temporary body. Most people need the mortal body striped away before they can see God/ Jesus as they are and will respond to reconcile only then,God is not bound by time, man tries to put that on God but he is not bound by our time table.
There are many scriptures we are told that its Gods plan to save all his creation and he will, Adams sin is not more powerful than Jesus and his sacrifice for all humanity.
