I often find myself ruminating on this. Some have had everything going against them and what of those with any kind of mental illness who couldn't think properly about anything, let alone the spiritual. I can't imagine God sending to eternal damnation those who just felt they couldn't trust anyone, those who feel defeated or overwhelmed due to circumstances beyond their control, those dealing with mental health issues, large or small, just to name a few. Also, how close do you have to come to be considered as having buried your talent in the ground instead of investing it?
Well He did tell St. Faustina that before He comes as the just judge He first comes as the King of Mercy!! Praise be to the Lord and praise be to His love and mercy that at least for now is greater than His just wrath!
Romans 11:34 “For who has known the mind of the Lord, or who has been His counselor” It’s probably not wise to speculate on who is going to Hell. Imho
