Naaji,
I want to think about your question a little longer to answer it, and I'm at the library and not at home, so I will reply a little later again to your question. Can I ask you to do one thing for me please? Read Luke 16 if you have access to a bible. If you don't, then please look in the online Bible. I know you don't believe that the Gospels are the "true word of God' but I want to show you something. I'll come back later and use Luke 16:19-31 as the basis for your answer to the question.. Why did God need to come in the flesh? I think what you have asked is THE most important question any human being can ask and I'll try and show you.
Thanks for hanging in there and keeping on this debate. I am learning lots .. not just about my own faith, but about yours too, and I respect you greatly for keep coming and discussing with us.
