CCC 1819

Christian hope takes up and fulfills the hope of the chosen people which has its origin and model in the hope of Abraham, who was blessed abundantly by the promises of God fulfilled in Isaac, and who was purified by the test of the sacrifice.⁸⁶ Cf. Gen 17:4-8; 22:1-18. "Hoping against hope, he believed, and thus became the father of many nations."⁸⁷ Rom 4:18.
