Who agrees that counterintuitively, eternal salvation is universal because morality is objective but relative? How? Why? My answer: morality is relative yet objective because reciprocity and harm avoidance are the objective moral roots yet, firstly the tradition, secondly the risk analysis, and thirdly the skin in the game, that moral practices derive from, can differ. As for the afterlife, God commands that we try our best in whatever predicament he plants us in(no individual chooses (insert pronoun) own genes, (insert pronoun) environment, and or (insert pronoun) self). Suffering may be philosophically justified by meaning. Free will is compatible with determinism(both are unfalsifiable and believing in each of them is a survival heuristic. Therefore, somethings in life are choices while others are not). Thus God is merciful upon mistakes and takes all into eternal salvation.
