The Second Letter of John is a brief but purposeful message written by the apostle John, likely to a local church symbolically referred to as “the elect lady and her children.” In it, John emphasizes the importance of walking in truth and love while also warning against welcoming false teachers who deny the true identity of Jesus Christ. It is a concise reminder that Christian hospitality must be grounded in discernment and doctrinal faithfulness.

John opens with a greeting grounded in truth, grace, mercy, and peace, affirming his joy that some members of the community are walking in obedience to God’s commands. He reminds the church that the command to love one another is not new but central to the Christian life, and that love is shown by walking according to God’s commandments.

However, John also warns of deceivers who have gone out into the world, denying that Jesus Christ came in the flesh. These individuals are not just mistaken, they are described as antichrists. The church is urged to guard what they have received so that they do not lose their reward by being misled.

John gives a strong caution: do not welcome or support those who bring a false teaching about Christ. Offering hospitality to them, he says, is participating in their wicked work. This instruction reflects the seriousness of preserving the truth of the gospel in the face of growing deception.

The letter closes with a personal note: though he has more to say, John prefers to speak face-to-face, expressing his desire for joyful fellowship. 2 John is a clear and concise call to balance love with truth, urging believers to practice discernment, maintain doctrinal integrity, and continue walking in obedience to Christ.
