Be hospitable one to another without grumbling.
hospitality: Thayer says the word "hospitality" means "hospitable, generous to guests, (given to hospitality)" (654-2-5382). Christians are to extend hospitality to others without "grudging," that is, without murmuring, muttering, or complaining. The word is used in Acts 6:1 of the murmuring of the Grecians against the Hebrews. Peter was a realist! He knew that the "use" of hospitality could become a burden and that Christians could be tempted to complain. The responsibility, the expense, the inconvenience are to be borne without complaint (2 Corinthians 3:1; 2 Corinthians 9:7).
