The New Testament Books of 1st, 2nd & 3rd John

In 1st John the author calls readers back to the three basics of Christian life: true doctrine, obedient living, and fervent devotion. Because “God is light”, Christ’s followers overcome evildoers who seek to subvert them. The one who lives in and among them—God’s Son—is greater than the spirit of “the antichrist” now in the world. To believe in the name of the Son of God is to know the assurance of eternal life.

The focus of 2nd John is living in the love of God in accordance with the truth of Jesus Christ. This love extends not only to God but to other people. It is also discerning; it does not “go on ahead” of biblical revelation, and it does not lend aid to enemies of the gospel message. Instead, Christ’s followers “walk according to his commandments” and through faith “win a full reward”.

The theme of 3rd John is steadfastness in the face of opposition. The recipient of the letter, Gaius, faces a troublemaker named Diotrephes. By “walking in the truth”, Christians can embrace and live out the apostolic message that John conveys in all his letters.
