With this single sentence, John lays bare the phoniness of so much religion; so much that calls itself Christian. This does not mean that followers of Jesus are sinless (see 1 John 1:8). It means that the rallying point, the central interest, the inspiration, instructor and guide for living is Jesus. A discipleship that lacks interest in the question; What would Jesus do? Is a falsehood.
