God’s “no partiality” is still particular even if the promise to Jews was extended to Gentiles. That doesn't mean the nature of the arrangement wasn't radically changed. God cut circumcision, the signature sign of the covenant, along with the restricted diet, the observance of days, the sacrifices, etc. But the new “no partiality” is still only shown to those who fear God and do what is right. That means in the most important way nothing has changed in that fearing God and doing what was right was always what God had in mind even if those who lived the outward signs failed to embrace the inward ways. God desires relationship not sacrifice. So how do we who are the recipients of the new “no partiality” repay the favor? I’m afraid we write new rules and make our peculiarities particular to God. Who knows if the God who gave up kosher to include those who think everything's better with bacon might also give up all things for the sake of those God always intended to include in the “no partiality” covenant. Who knows? What we do know is that God determined to die hanging on a tree for the sake of those who could care less which may mean God is partial even to those who fail to fear God and do what is right.
