“Who will hug everybody?”
That was one of the questions our friend Steve asked after he got the news that he had cancer and realized he would be away from our church for a while. Steve is the kind of man who makes everyone feel welcome—with a friendly greeting, a warm handshake, and even a “holy hug” for some—to adapt an application from Romans 16:16, which says, “Greet one another with a holy kiss.”
And now, as we pray for Steve that God will heal him, he is concerned that as he goes through surgery and treatment—and is away from our church for a time—we will miss out on those welcoming greetings. 
Perhaps not all of us are cut out to greet one another as openly as Steve does, but his example of caring for people is a good reminder to us. Notice that Peter says to “offer hospitality to one another without grumbling,” or in a way that centers on love (1 Peter 4:9; see Philippians 2:14). While first-century hospitality included offering accommodations to travelers—even that always starts with a welcoming greeting.
As we interact with others in love, whether with a hug or just a friendly smile, we do so “that in all things God may be praised through Jesus Christ” (1 Peter 4:11).
