Before I write this, I want to state that the below is my personal opinion, does not reflect on the site and is different than the other mods. Feel free to disagree or push back on it.
I am a nontheist (Buddhist) and do not believe in life after death. I left Christianity shortly after earning my Masters in Theology. Before I left the faith, ideas similar to what
@New_to_OKC posted resonated with me a great deal: Process Theology, Panentheism and Christian Mysticism in particular.
Thanks for sharing your thoughts.
The Christian Bible says that nobody can believe in Jesus unless God the Father permits them to do so. The same is true for repentance (changing). Many will go to the grave having never believed but, in the hereafter, they too will eventually be permitted to believe and repent and follow Jesus, or so I believe based on the Bible.
Belief in Jesus:
Ephesians 2:8-9
8 For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, 9 not a result of works, so that no one may boast.
Romans 11:25
25 Lest you be wise in your own sight, I do not want you to be unaware of this mystery, brothers: a partial hardening has come upon Israel, until the fullness of the Gentiles has come in.
John 6:44
44 No one can come to me unless the Father who sent me draws him. And I will raise him up on the last day.
The ability to repent/change:
