The problem is THERE ARE NO GOOD PEOPLE ...LUKE 18:19 Why do you call me good?" Jesus answered. "No one is good--except God alone.
Understood - the book was written by a Jewish Rabbi, but the insights are still valid regarding the reason that we suffer from sin and that we have free will.
He wrote it to answer one of the most asked questions he received. Something along the lines of: If God is omnipotent why does he let people suffer? from an innocent baby in the world less than x months to a sacrificing adult...he used a number of examples from his rabbinic service. He said the hardest were the parents asking about how their children could warrant it - and he had a personal example as well.
Still a good book
