Mother Theresa told of her calling to be a servant to what the world would call unlovely, not worthy of high regard, the lepers, the poor and the needy.  It came about when she realized this truth – Respect the WHO.  She was on a crowded bus in India.  The smell, the sight of all those poor, dirty, sick people literally made her sick.  She found herself judging them.  And in that moment she realized that all of those souls were Christ in a distressing disguise.  She came to respect with high regard each person no matter what they were disguised as.
