 The second problem which confronts us is more difficult, and also more important. John uses three titles of the people to whom he is writing. He calls them little children; in 1 John 2:12 the Greek is teknia ( G5040) and in 1 John 2:13 paidia ( G3816) ; teknia ( G5040) indicates a child young in age and paidia ( G3816) a child young in experience, and, therefore, in need of training and discipline. He calls them fathers. He calls them young men. The question then is: to whom is John writing and three answers have been given.
