Book of Isaiah 40,25-31.
To whom can you liken me as an equal? says the Holy One.
Lift up your eyes on high and see who has created these: He leads out their army and numbers them, calling them all by name. By his great might and the strength of his power not one of them is missing!
Why, O Jacob, do you say, and declare, O Israel, "My way is hidden from the LORD, and my right is disregarded by my God"?
Do you not know or have you not heard? The LORD is the eternal God, creator of the ends of the earth. He does not faint nor grow weary, and his knowledge is beyond scrutiny.
He gives strength to the fainting; for the weak he makes vigor abound.
Though young men faint and grow weary, and youths stagger and fall,
They that hope in the LORD will renew their strength, they will soar as with eagles' wings; They will run and not grow weary, walk and not grow faint.
"Come to me, for I am meek and humble of heart" (Mt 11:28-29)
Peculiar to a star is the light that surrounds it. And peculiar to those who worship and fear God are poverty and humility. For there is nothing so distinctive nor is there so plain a sign of the disciples of Christ as a humble spirit and an unpretentious appearance. All four gospels speak of this. Those who do not live humbly in this way lose their portion in him who humbled himself even to the cross and to death (cf. Phil 2:8), he who was also the lawgiver and has out into practice the commandments of the holy gospels. It is said: "Come to the waters, you who are thirsty" (Is 55:1). You who are thirsty for God, come to purity of thought. For there is none higher than the humble. As when there is no light all things are obscure and dark, so when there is no humility all our acts are foolish, vain and barren. (…) The soul that is benefited and sweetened by Jesus repays its benefactor, acknowledging him with exultation and love. And it render thanks and with sweetness of heart calls upon him who gives peace. For it sees him, within itself, disperse the fantasies of evil spirits. (…) So let us practice prayer and humility, those two weapons with which, together with sobriety, spiritual warriors arm themselves against the demons as with a flaming sword. If we live thus we shall be able to hold in our hearts a secret feast of rejoicing every day and every hour. (…) The Lord has said: "Learn from me for I am meek and humble of heart, and you shall find rest for your souls." (Mt 11:29).
