Is the second "theological virtue" along with → faith and → charity. This is not only to trust and wait in the saving intervention of God, as is often found in the OT (cf. P.E. Sal 40.2) but a gift of the Holy Spirit that through his grace orients the intentional faculty of the human spirit divinely. It is the certain, blessed energetic and desirous expectation of future glory. The certainty of hope derives from the faith it provides as a foretaste of the separate realities (cf. Hb 11.1); joy comes from the fact that hope is an ecstasy of the spirit towards the fullness of salvation, of which the firsts are already possessed (cf. P.E. 2 Co 5.4-10); the energy or operosity of hope depends on its nexus with charity; hope is an active tension, which wants to anticipate and hasten the arrival of the definitive Kingdom by "sowing in the Holy Spirit" with an existence of love (cf. Ga 6.7-8). The very existence of hope is a persevering extend forward of desire (cf. Rm 8.25). The three virtues are like three sisters: the two elders, Faith, and Charity carry the hand to the sister, Hope, but this one drags to the other two where she wants (Péguy).
