Introduction to the Third Epistle of John.
The wise elderly apostle John wrote this brief letter about the same time he wrote
1 John and 2 John, toward the end of the first century.
John sent this third letter to a man named Gaius.
Gaius often showed hospitality to traveling teachers and missionaries.
John praised his generosity, but also warned him about a man who was refusing to
listen to spiritual leaders in authority.
Notice John's warmth even in this troubling situation.
