Albert Barnes Commentary 1 Peter 4:9

"using hospitality one to another without murmuring:" — 1 Peter 4:9 (ASV)

Use hospitality one to another. On the duty of hospitality, see the notes on Romans 12:13 and Hebrews 13:2.

Without grudging. In Greek, this is "without murmurs"; that is, without complaining of the hardship involved, such as the time, expense, and trouble required. The idea of grudging in the common sense of that word—meaning doing it unwillingly, regretting the expense, considering it ill-bestowed, or viewing it as not producing any equivalent—is not precisely the idea here. It means that we are to do it without murmuring or complaining. The value of hospitality is greatly enhanced when it is done on our part with entire cheerfulness. One of the duties involved is to make a guest happy, and this can be done in no other way than by showing them that they are welcome.
