Humility does not spring up in our souls of its own accord. On the contrary, every child of Adam has a deep root of pride within his soul. It is only by a long and painful process that the generality of mankind can attain humility. We cannot expect to become humble unless we fulfill the necessary conditions.
We must make many acts of humility before we can attain any proficiency in the virtue. Our acts of humility must consist not merely in protesting to Almighty God that we are vile and worthless in His sight and in humbling ourselves before Him by reason of our many sins. Our They must be practiced towards others by being very gentle towards those who provoke us, by bearing contradictions with patience, by accepting disappointments with patience and rebuffs without complaint. All this is a gradual process and we must not expect proficiency in humility until we have long practiced these means to attain it.
We must pray for humility. No gift of God can be won without prayer and humility least of all, because it is so opposed to the natural bent of our nature, and can never be had without a special grace from God. Prayer, moreover, is an acknowledgement of our dependence on God, and humility consists in nothing else than a recognition of this dependence and an acquiescence in it. Pray, then, for humility.
It is not much use praying for humility unless we also pray for the means that are to implant it in our souls. We must ask God from our hearts not to spare us if He sees that we shall not become humble without suffering. We must leave ourselves in His hands, saying only, "O my God, make me humble at any cost!"
