I came across an old prayer card in one of the antique books I put up for sale on Ebay. It offers a quote from St. Therese and Suffering: The Spirituality of St. Therese in Its Essence by Abbe Combes. I'm not sure if it is a quote by St. Therese or about her, but I thought that it was worth sharing:
Everything is a grace, everything is the direct effect of our Father's love - difficulties, contradictions, humiliations, all the soul's miseries, her burdens, her needs - everything, because through them, she learns humility, realizes her weakness.
Everything is a grace because everything is God's gift. Whatever be the character of life or its unexpected events - to the heart that loves, all is well.
St. Therese, pray for us.
