23. Examine those virtues which you imagine that you possess. Have you prudence, temperance, fortitude, justice, modesty, humility, chastity, humbleness of spirit, charity, obedience, and many other virtues that may be necessary or suitable to your condition? If you have a few of these, in what degree do you possess them?

But I will say more: and that is, examine yourself first, and see whether you really have this virtue that you think you possess. What I mean to say is: is it a real virtue, or perhaps only a disposition of your natural temperament, be it melancholy, sanguine or phlegmatic? And even should this virtue be real, is it a Christian virtue or purely a human one? Every act of virtue which does not proceed from a supernatural motive, in order to bring us to everlasting bliss, is of no value. And in the practice of virtue, do you join to your external actions the inward and spiritual acts of the heart? O true Christian virtues, I fear that in me you are nothing but beautiful outward appearances! I deserve the reproach of God's word: "Because thou sayest: I am rich, and made wealthy, and have need of nothing; and knowest not that thou art wretched and miserable, and poor and blind and naked." [Apoc. iii, 17] And in the same manner the counsel of St. Augustine is good for me, that it is better to think of those virtues in which we are lacking rather than of those which we possess. "I will humble myself more for those virtues which I lack than pride myself on those I possess." [In Ps. xxxviii]
