A story of St. Nicholas Velimirovich tells us the difference between doing something good and doing it in Jesus’ Name. One day the Bishop met an old peasant woman at a tiny railroad station in Matchva. He asked, “Whom are you waiting for, sister?” “Whomever the Lord sends me,” she answered. It turns out that this woman came every day to the station in order to see if some poor traveler might need food or shelter. If someone showed up, she would joyfully accept him into her house. When the Bishop tried to praise her gospel-like hospitality, the woman sighed and saying, “Aren’t we His daily guests throughout all our life?”.
