We are encouraged to welcome strangers, for by doing so, many people have entertained angels unaware (see Hebrews 13:2). As Jesus put it in his only description of the final judgment, “in so far as you did this to one of the least of these, you did it to me” (Matthew 25:40). I wonder what else could save us from our fear and accusation of one another, except one whose judgments are both upside-down and true—and whose mercy is everlasting. Fortunately, they are one and the same, a God who is both sanctuary and stumbling stone (see Isaiah 8:14).
