I like all annotations of the Sermon on the Mount, because I like certain parts of it (but not others). These are my private limitations and restrictions, part of my individuality, which I must give up to be more open to Jesus and our Father, God.
But are we really God's children? What Mr. Fox leaves out, which has been emphasized elsewhere in commentaries, is that Jesus Christ differs from other prophets in one thing: He rose from the dead. Muhammad didn't do this, Buddha didn't do this, Yogi Parmansa (who?) didn't do this. But did Jesus really come back to life after dying? This is the crux of the matter, and this is where faith comes into play.
Assume, for a moment, that I'm not sure Jesus did come back to life (there's some other explanation for what is written in the Bible). Still, I like what he said about the birds of the air and the lillies of the field, about turning the other cheek, about letting the suer have your two coats, non-resistance and just getting along. Mr. Fox, on the other hand, obviously has no doubts about Jesus being Divine, so everything else just follows naturally.
I would like to see a little more light on the issue than just to assume first (a) and therefore, b, c, and we're sons of God. Are we really? I know, have faith or be damned.
Well, riding the bus one day, two males in the back were talking, one saying how prostate cancer was very prolific among American males. I could feel the other men on the bus crossing their legs, looking suddenly worried, until the second man spoke up in a loud voice, "Well I'll be damned!" he said. Aren't we all?
