I am at present writing a summary of my credo to my grandson. In it I address the problem of evil when considering the existence of God. This blog is good on this subject.

Oliver Leaman, Evil and Suffering in Jewish Philosophy (Cambridge Studies in Religious Traditions) (Paperback)

I read this last year. It takes Job as the centre of its inquiry which is a very useful and clear consideration of key issues.

Thanks for the comment Abailart. The book looks a bit daunting certainly as far as the cost goes. I will ask our local library to get it for me
