Don't forget, in an existence that does contain eternal punishment, everyone who had half a heart who was aware of this eternal punishment would be frantically running around trying to save as many souls as they possibly could, because of the simple fact that this life is infinitely short when compared with eternity. Engaging in leisurely activities while on this earth would be uncharacteristicly selfish considering what looms eternally after this brief worldly existence.
Period.
IOW's if you are incorrect in your understanding on this subject God is not whom he claim Himself to be in scripture. It's God not you who is unloving.
