I don't have time to elaborate now, but Rom. 3:1-4a should be helpful in understanding God's covenant to unbelievers in the covenant.
"What advantage then has the Jew, or what is the profit of circumcision? Much in every way! Chiefly because to them were committed the oracles of God. For what if some did not believe? Will their unbelief make the faithfulness of God without effect? Certainly not!"
Indeed, the Jews had the inside track. And yes, their unbelief cannot undo God’s faithfulness to the Israel of God, the elect to whom the promises pertain - the children of promise.
