Marilynne Robinson said this quote

When you encounter another person, when you have dealings with anyone at all, it is as if a question is being put to you. So you must think, What is the Lord asking of me in this moment, in this situation? ... This is an emissary sent from the Lord, and some benefit is intended for me, first of all the occasion to demonstrate my faithfulness, the chance to show that I do in some small degree participate in the grace that saved me, you are free to act otherwise than as circumstances would seem to dictate.
