A few years ago I spent some time at a monastery in Southwestern Missouri. While there I found the following words scribbled on a wall:
They may see the good you do
as self serving.
Continue to do good.
They may see your generosity
Continue to be generous.
They may see your warm
and caring nature as a weakness.
Continue to be warm and caring.
For you see, in the end,
it is between you and God.
It was never between you and them.
