The house of the elect lady (2 John) was the sanctuary of the truth, and had to keep outside all that was not of it: all those that did not bring the doctrine of Christ with them. The house of Gaius (3 John), on the contrary, was the guest chamber of the truth, and had to open itself to the witnesses of it. She was to be the guardian of this mystery—he, the fellow-helper of it.
Shall we not all join in such services as these? Surely all this is Kohathite service—this is business with the ark itself. Oxen and wagons could not aid in it. (See Num. 7.) The material of the service is too delicate for such help. The shoulders of the Levites must do the service, and even their hands must reverently, and only reverently, handle the sacred deposit committed to them.
