Where does St. Augustine say - - "Hope has two beautiful daughters : Anger & Courage" ?

Today (Dec. 16, 2007) in the Sermon by Rev. T. Kyle Gardner (interim pastor/preacher St. John's UCC, Niles, Michigan 49120) he shared during his sermon on Waiting and Holy Patience the sermonic quotation from the noted church father of the 4th Century, St. Augustine of Hippo - -

Hope has two beautiful daughters - - Courage and Anger. . .

Can you tell me where in the course of the Church Father's sermons and doctrinal writings/Biblical commenting does he draw this illustration or observation ?

Thanks for replying and posting as possible!

Can you tell how much a person relies on faith?

Greetings, readers and interested from all kinds of places in the World Wide Web!

I have just begun this Blog to ask questions and to provide the subjective answers I can supply. God bless you if you too are seeking

Faith and Understanding with your heart, soul, and mind.

My next posting concerns a question from the Sunday 10:30 a.m. worship here in Niles, Michigan (Berrien County, SW corner of Lower Peninsula).

Thanks for taking some time to be in dialogue on critical matters.
