As Jews, Christians and Muslims, we have to be prepared to ask the most uncomfortable questions. Does the God of Abraham want his disciples to kill for his sake? Does he demand human sacrifice? Does he rejoice in holy war? Does he want us to hate our enemies and terrorise unbelievers? Have we read our sacred texts correctly? What is God saying to us, here, now? We are not prophets but we are their heirs and we are not bereft of guidance on these fateful issues.
