John the beloved apostle in his three epistles challenges and encourages his readers to authenticity (i.e., being real!!!). The first epistle focuses on the evidence that a person is born of God. The genuine believer enjoys the fellowship with the Father and the Son and with all other believers.

The second epistle commends authentic living - walking in truth and having no part with what is anti-Christ. Christ is the embodiment of truth (John 14:6) - So hold fast to the doctrine of Christ!

The third epistle continues the same theme of the second, with the emphasis on walking in truth, helping the truth and maintaining good works in keeping with the truth.

There are four men mentioned in the epistle, the elder (John the author), Gaius the recipient, Diotrephes and Demetrius... The little mentioned about them in this epistle provide some valuable lessons on living authentic Christian lives because of the Truth.
