Here is some of my reflection after studying those eight letters rich with water imagery:
When we look honestly at our utter poverty we see the outstretched arms of the Risen Lord who desires that we come to Him. We can trust the Lord Jesus with our broken lives in utter confidence that the Holy Spirit covers what is broken, what causes us shame, honoring every bit and has already begun the rebuilding process.
In Catherine of Siena's writing, as in all wisdom literature, there is an unrelenting call to be made whole, to experience the mercy and love of God embracing our utter poverty.
