The Lost Love of Hospitality

3 John 1:5-8 Beloved, it is a faithful thing you do in all your efforts for these brothers, strangers as they are, who testified to your love before the church. You will do well to send them on their journey in a manner worthy of God. For they have gone out for the sake of the name, accepting nothing from the Gentiles. Therefore we ought to support people like these, that we may be fellow workers for the truth. 
John commends Gaius for something that may not seem like much of a big deal to many of us: the hospitality he had shown to traveling evangelists and teachers.  But very quickly he shifts gears, changing to the future tense, encouraging Gaius to keep up this biblical practice.  Why? Positively, it is important that these itinerant preachers had a safe place to stay in an age when few such places were available, and because of the possibility to get to know these men, and to be a part of their ministry.  But negatively, as we will see, it appears that the art, the love of hospitality was becoming lost.  Some not only failed to do it; they discouraged it.  Where is this love, this art, in our society?  We are missing out on so many blessings, getting to know and share with so many fellow believers and how they live out their faith.  We rob ourselves, and the church of blessings God wants to send our way.
