Here is the second part of my rephrase. I'm finding it difficult to summarize the last paragraph.

1) In the second passage (excerpt) Robinson instructs Friday in the Christian religion. Friday, on the other hand, comments on the difference between Christianity and his own religion.
2) Friday seems to be favourably disposed towards the Christian religion and he seems to consider Robinson’s teaching with high respect.
3) Robinson teaches him that God is the great Maker who can do everything for us but can also take everything from us. In particular, Friday receives with pleasure the notion of Jesus Christ being sent to redeem humans and he is glad to learn that Christian prayers are so powerful that they reach (be heard?) into heaven.
4) Friday tells Robinson that their God can’t be heard by humans because he lives on the great mountains and only the old priests go up to him (?) to say their prayers. When they come back they report them what their God, Benamuchi, tells them.
