3 john has three lessons for us: 1) practice hospitality and generosity, especially to missionaries or teachers of the Word 2) continue to walk in the truth, and 3) do what is right. 3 John is a letter to a fellow named Gaius who had a great reputation for always offering his hospitality and friendship to traveling missionaries and teachers. John says we should "support them so that we may become partners with them for the truth", for they are "traveling for the Lord". Gaius is an example of a faithful, selfless servant that we should strive to be like as we encounter opportunities to help those in God's ministry.
