Ad,
However we also know that many reject God and therefore through their own choice will be excluded from heaven.
Does it not seem to you peculiarly narcissistic and arbitrary of this God of yours to make the selection criterion whether or not people “reject” him rather than, say, find a cure for cancer, foster needy children, or do similar good works that benefit “His” special creation?
What kind of moral monster would condemn someone to an eternity (an eternity mind you) of cloven-footed types with toasting forks just because they didn’t show “Him” sufficient obeisance while on the mortal coil?
