It was a real question, lily, not a tease. I really have never understood how one could tell, and that in spite of eighteen years of full on religious teaching by family and school. However, if you're happy with evidence that many people cannot access, so be it. The trouble is, some people have quite extreme views about what god's will is, and end up doing things that the rest of us think are criminal. How is that explained? Clearly, there is confusion about god's will to say the least, or there would never be any discussion, and there has been. Religious rules have been changed, even. Does god's will change according to the culture of the time? It would seem so to a mere mortal like me.
