This image from one of the Desert Fathers has been coming back to me of late:
An elder was asked by a certain soldier if God would forgive a sinner. And he said to him: Tell me, beloved, if your cloak is torn, will you throw it away?
The soldier replied and said: No, I will mend it and put it back on.
The elder said to him: If you take care of your cloak, will God not be merciful to his own image?––Quoted in Thomas Merton's The Wisdom of the Desert, n. 139
The image is used in a classic Steve Taylor song which I just recently heard as a killer cover by Fleming and John.
