So by that doctrine, you could spend a long life hurting and destroying others, or wrecking the planet (or the universe that god created) so that no other living creature could have any kind of existence, and then when death is near and the mouth of hell is yawning before you, you could earn eternity in heaven by saying the right thing?
But if you spent that life helping others, saving lives, preserving the wonders of the planet the further stars and universe, because you loved your fellow-men and you valued the miracle of creation, you would then spend eternity in hell?
Do you have children? Would you only feed and clothe the ones who admitted that you were the boss and the most wonderful mother or father that ever existed?
A father who condemns his children to damnation until they worship him would be condemned himself for emotional abuse.
