a Kempis on Humility

For by the grace given to me I say to everyone among you not to think of yourself more highly than you ought to think, but to think with sober judgment, each according to the measure of faith that God has assigned.  - Romans 12:3

The saints who are highest in God's sight are the least in their own: and the more glorious they are, the more humble they are in heart, full of truth and heavenly joy and not desirous of vainglory.
Being grounded and confirmed in God, they can in no way be proud.  They who ascribe to God whatever good they have received do not seek glory from one another, but only that glory which is from God; and the desire of their hearts is that God be praised in Himself and in all his saints, and to this end they always tend.

-St. Thomas a Kempis (14-15th Century spiritual writer)
