3 John 1:6

who bare witness of thy love before the church: whom thou wilt do well to set forward on their journey worthily of God:

This is a description of the "witnessing" mentioned in 3 John 1:1:3, which see. One may glimpse the enthusiasm and excitement of 1century evangelism in the thoughts here.

Set forward on their journey ... "The Greek works used here imply not only good wishes, but material support."[18] The New Testament custom of congregations accompanying such travelers a part of the way upon their departure is glimpsed again, and again, in the account of Paul's travels in Acts.

Worthily of God ... indicates that Gaius was to go the whole way in his hospitality. It meant, "to help on one's journey with food, money, by arranging for companions, and providing means of travel."[19] Dodd went so far as to declare that "set forward on their journey" was somewhat of "a technical term of early Christian missions, implying the assumption of financial responsibility for departing missionaries."[20] This would seem to be true. Certainly, Paul seems to have had in mind the financial support of brethren in Rome for his projected trip to Spain.
