He was pulling my leg, but there was a serious point behind what he was saying. This is perhaps the religious view of “good enough doctoring”. We should try to do the best we can, but we shouldn't be too harsh on ourselves when we fail. I suspect that people who are driven by religious duty, or shamed by weight of guilt, do not find it easy to imagine that God might forgive them. But as the hymn says: “Father-like he tends and spares us, well our feeble frame he knows”. And a little earlier, during the intercession, we had said this prayer:
We pray for ourselves, God.
You know each of us by name.
Make us into the people you want us to be,
and when that hurts,
reassure us how much you love us.
