He ended by relating about learning the theory of limits in calculus, "Where you are to find the value of the area under a curve, that the function gets infinitely close to, but never actually reaches." He compared this to the quest of "achieving sainthood, which might seem impossible, but, unlike the function in calculus that never actually reaches that point, you can reach sainthood through the grace of God. All you have to do is persevere, as St. Josemaría Escrivá says, 'To begin is for everyone, to persevere, for saints!'”
