3 John 1:5 Beloved, thou doest faithfully whatsoever thou doest to the brethren, and to strangers;
6 Which have borne witness of thy charity before the church: whom if thou bring forward on their journey after a godly sort, thou shalt do well:
Theses verse help us to see that we need to practice hospitality not only toward those whom we know but also to those whom we do not know. We should be filled with hospitality for all the Christian brothers, whether they are strangers to us or not. Our reputation for hospitality and kindness, as well as obedience should be practiced to the degree it is known to others. We should encourage others to practice a Godly hospitality to all they come in contact with. We should know that when we treat people as God would treat them we are doing it in manner that hospitality should be practiced. We would do well to be as good a servant to God as Gaius was.
