Once I was pondering why our Lord was so fond of this virtue of humility, and this thought came to me — in my opinion not as a result of reflection but suddenly: It is because God is supreme Truth; and to be humble is to walk in truth, for it is a very deep truth that of ourselves we have nothing good but only misery and nothingness. Whoever does not understand this walks in falsehood. The more anyone understands it the more he pleases the supreme Truth because he is walking in truth. Please God, Sisters, we will be granted the favor never to leave this path of self-knowledge, amen.
