"In that sense Israel’s lack of righteousness was because of their lack
of trusting faithfulness and, in turn, the reason why they didn’t fully
recognise and embrace the Messiah. I agree that the goal of faith is
the right relationship of a people of God that is demonstrated by that
blend of character and service that is implied by this understanding of
"trusting faithfulness" - to calling, to the very person of Jesus…"

Couldn’t it also be argues that the people of Israel where simply following God’s rules by not embracing Jesus as the Messiah?  Afterall - the first commandment was "You shall have no other Gods but me."  Giving the people of Israel the benefit of the doubt one could say that to believe in someone embodying God on earth would be a violation of the very first commandment.
