From my book “Humility of Heart” by the Catholic Fr. Cajetan Mary da Bergamo:
Empty vessels not a few (4 Kgs 4:3) And He also fills with His grace those hearts which are emptied of self - that is to say, which have neither self-esteem nor self-confidence and do not rely upon their own strength.
This is the way of the truly humble: he does not esteem himself for his possessions or for his knowledge, but regards these all as nothing, because he regards himself also as nothingness.
It is very easy for us to fall into this fault of praising ourselves, until it becomes a habit, and with this habit so opposed to humility, how can we be humble? What good qualities have we of our own for which we can praise ourselves? All the good that is in us comes from God, and to Him alone we must give praise and honor. When we praise ourselves we are usurping glory, which is due to God alone. Even though in praising ourselves we sometimes refer all the honor to God, it matters little; when there is no absolute necessity, it is better to abstain from self-praise, for although we refer all to the glory of God with our lips, our ingenious and subtle self-love cannot fail to appropriate it secretly.
I am poor in soul, without virtue or merit, full of iniquity and malice, and yet I esteem myself and love my esteem so much that I am troubled if others do not esteem me also.
Make known unto me O Lord, mine own wretchedness, that of myself I am nothing, know nothing, and possess nothing but my sins, and deserve nothing but hell.
We must acknowledge that one of the five reasons we do not live in this necessary humility is that we do not fear the justice of God…The soul conscious of the innumerable sins he has committed, aware that it has indeed deserved hell, and that from one moment to another it may be condemned to hell by Divine Justice, fears the wrath of God; and this fear causes the soul to remain humble before Him; and if he does not feel this humility, it can only be because the fear of God is wanting.
But in reality a lie dwells essentially in that pride which makes us esteem ourselves above what we are. Whoever regards himself as more than mere nothingness is filled with pride and is a liar. It is St. Paul’s statement: "If any man think himself to be something, whereas he is nothing he deceiveth himself (Gal. 6:3)
The more esteemed you are on judgment day the worse it will be for you.
