Hospitality was essential in the early church: an open house for other Christians coming through -- teachers, apostles, prophets or people fleeing persecution.
Peter calls the church to do it without grumbling though. Without resentment.
Grumbling hospitality? That’s oxymoronic. Why would you resent it? Because it involves time, resources, and energy. It’s costly. Hospitality is fundamentally not about us. It’s about the other person. Maybe in the first century the Christians said, “Wow, I sure wish Paul and Barnabas would move on to the next town!”
But remember how Christ’s hospitality has reconciled you:
He gave up his home (Phil 2:7)
to become homeless (Matt 8:20)
that we might be brought back into His home (John 14:2).
Jesus is the basis of true hospitality, not Martha Stewart.
