kept in heaven for you
who by the power of God are safeguarded through faith,
to a salvation that is ready to be revealed in the final time.
In this you rejoice, although now for a little while
you may have to suffer through various trials
--1 Pt 1:3-9
Fortitude is the moral virtue that ensures firmness in difficulties and constancy in the pursuit of the good. It strengthens the resolve to resist temptations and to overcome obstacles in the moral life. The virtue of fortitude enables one to conquer fear, even fear of death, and to face trials and persecutions. It disposes one even to renounce and sacrifice his life in defense of a just cause. "The Lord is my strength and my song." "In the world you have tribulation; but be of good cheer, I have overcome the world."
-- CCC 1808
