I thought that perhaps you thought God was love and would somehow benefit his believers. If you think that 'the same ritual prayers, that they have the same identical scripture, that they fast during the same month and over the same duration of the day etc etc' is proof of God's backing, I just don't see it.
You often give the impression that in the Bible, only the words of Jesus are reliable. What do you make of these words?
(John 13:35) By this all will know that you are my disciples—if you have love among yourselves.”
(Matthew 7:20) Really, then, by their fruits you will recognize those men.
