Hope
[1817] Hope is the theological virtue by which we desire the kingdom of heaven and eternal life as our happiness, placing our trust in Christ’s promises and relying not on our own strength, but on the help of the grace of the Holy Spirit. "Let us hold fast the confession of our hope without wavering, for he who promised is faithful."84 "The Holy Spirit . . . he poured out upon us richly through Jesus Christ our Savior, so that we might be justified by his grace and become heirs in hope of eternal life."85
[1818] The virtue of hope responds to the aspiration to happiness which God has placed in the heart of every man; it takes up the hopes that inspire men’s activities and purifies them so as to order them to the Kingdom of heaven; it keeps man from discouragement; it sustains him during times of abandonment; it opens up his heart in expectation of eternal beatitude. Buoyed up by hope, he is preserved from selfishness and led to the happiness that flows from charity.
[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 "Hoping against hope, he believed, and thus became the father of many nations."87

[1821] We can therefore hope in the glory of heaven promised by God to those who love him and do his will.92 In every circumstance, each one of us should hope, with the grace of God, to persevere "to the end"93 and to obtain the joy of heaven, as God’s eternal reward for the good works accomplished with the grace of Christ. In hope, the Church prays for "all men to be saved."94 She longs to be united with Christ, her Bridegroom, in the glory of heaven:
