"1 Peter 4:8–9 says, "Above all hold unfailing your love for one another, since love covers a multitude of sins. Practice hospitality ungrudgingly to one another."
Ungrudgingly! That means, be the kind of people who do it and like to do it! In other words the command to be hospitable is not just a command to do something. It is not just a command that can be legalistically fulfilled with a quota of guests. It is a command to be a certain kind of person, namely, the kind that doesn't resent having to be hospitable. The kind of person who doesn't look at the extra dishes and bedding and bother—and grumble. "Practice hospitality ungrudgingly to one another." Without murmuring. As the next verse (4:10) implies, let your hospitality be an extension or an overflow of God's hospitality to you. Be a good steward of God's grace.....
the most natural thing in the world is to neglect hospitality. It is the path of least resistance. All we have to do is yield to the natural gravity of our self-centered life, and the result will be a life so full of self that there is no room for hospitality. We will forget about it. And we will neglect it. So the Bible bluntly says, "Stop that!" Build a launching pad. Fill up your boosters. And blast out of your self-oriented routine. Stop neglecting hospitality. Practice hospitality." - John Piper
Let love be genuine; hate what is evil, hold fast to what is good; love one another with brotherly affection; outdo one another in showing honor. Never flag in zeal, be aglow with the Spirit, serve the Lord. Rejoice in your hope, be patient in tribulation, be constant in prayer. Contribute to the needs of the saints, practice hospitality.
