Warning Concerning Antichrists

In 1 John 2:18-28, the author warns against false teachings and false prophets who claim to have knowledge of the truth but deny Jesus as the Christ. He emphasizes the importance of abiding in Christ and following his commandments, as those who do so will remain in him and have eternal life. The author also encourages his readers to hold fast to the truth they have been taught from the beginning, and to remain in fellowship with one another as they wait for the return of Christ.
