Truth is the theme 3 JOHN, just as it was the theme of 2 JOHN. But it’s also a call to show hospitality to others, especially to those who were faithful teachers of gospel truth. In 2 JOHN, the apostle John went to great lengths to warn the Elect Lady, to whom he was writing, that under no circumstances was she to show hospitality to travelling false teachers who didn’t pass the sniff test of doctrine. In 3 JOHN, the apostle goes to great lengths to warn Beloved Gaius, to whom he is writing, that under no circumstances was he to deny hospitality to traveling teachers who did in fact pass the sniff test of doctrine.
