St. Teresa of Avila
Her works on prayer are considered to be some of the greatest pieces of spiritual literature ever composed. Once when God told her to bring a message to someone she replied, “Why do you give me this trouble? Can’t you speak directly to him?” She wrote:
Let nothing disturb you.
Let nothing frighten you.
All things pass away.
God never changes.
Patience obtains all things.
He who has God finds he lacks nothing.
God alone suffices.
St. Teresa’s autobiography is called The Book of Her Life and was written under obedience to her superiors.
