He tells people that they can no more expect justice in the afterlife than in the mortal plane, but he doesn't do this to dissuade them from worshipping God; on the contrary, he encourages them to do so. What he insists on is that they not love God under a misapprehension, that if they wish to love God, they be prepared to do so no matter His intentions. God is not just, God is not kind, God is not merciful, and understanding that is essential to true devotion.
