We examine the last of John’s three letters and conclude this sermon series, Letters to Humanity. John’s second and third letters apply the principles of 1 John, which test love and true faith in Christ to specific situations. In 2 John, the situation involved traveling teachers who did not confess truth about Jesus. The “elect lady” was not to extend hospitality to them. In 3 John, the situation also involved hospitality. This time involving three characters: Gaius, Diotrephes, and Demetrius and their response to the trials in proclaiming the truth in love with the issues of fellowship and hospitality.
