From Paul and the Faithfulness of God, page 911:
Here, then, is Paul’s vision of how the Messiah, particularly in his death and resurrection, had redefined around himself the very grammar of election, looking all the way back to Abraham. The patriarch believed, and was declared for ever ‘in the right.’ His seed would be enslaved within a land not theirs; God’s faithfulness would guarantee both Passover and promise: inheritance, and blessing for the world. They waited. Psalms and prophets sang of peace, a covenant of justice. And, instead: exile; hope lost; the rise of bestial empires. Then, which the times and tears had overflowed, God sent his only son, the strangest king, to be for Israel what they could not be: obedient; faithful; Passover in person. He was the seed, the servant, and the son; the chosen; the beloved; the victory won.
