The elder writes a short personal letter to the “chosen lady and her children” during the final decades of the old covenant age. Many deceivers have already gone out. The danger is not that the truth is unknown, but that some are departing from the teaching already received. The letter calls the recipients to continue walking in truth and love, and to refuse any teacher who denies that Jesus Christ came in the flesh.
1 The elder, to the chosen lady and her children, whom I love in truth, and not I only, but also all those who know the truth, 2 for the truth’s sake, which remains in us, and it will be with us forever: 3 Grace, mercy, and peace will be with us, from God the Father and from the Lord Jesus Christ, the Son of the Father, in truth and love.
4 I rejoice greatly that I have found some of your children walking in truth, even as we have been commanded by the Father. 5 Now I beg you, dear lady, not as though I wrote to you a new commandment, but that which we had from the beginning, that we love one another. 6 This is love, that we should walk according to his commandments. This is the commandment, even as you heard from the beginning, that you should walk in it.
7 For many deceivers have gone out into the world, those who don’t confess that Jesus Christ came in the flesh. This is the deceiver and the Antichrist. 8 Watch yourselves, that we don’t lose the things which we have accomplished, but that we receive a full reward. 9 Whoever transgresses and doesn’t remain in the teaching of Christ doesn’t have God. He who remains in the teaching has both the Father and the Son. 10 If anyone comes to you and doesn’t bring this teaching, don’t receive him into your house, and don’t welcome him, 11 for he who welcomes him participates in his evil deeds.
12 Having many things to write to you, I don’t want to do so with paper and ink, but I hope to come to you and to speak face to face, that our joy may be made full. 13 The children of your chosen sister greet you. Amen.

The elder greets the chosen lady in the truth that already remains in them and will be with them forever. Grace, mercy, and peace are not postponed gifts. They flow now from the Father and the Son. The letter opens with settled reality, not with future expectation. The truth is present. The relationship is already established.
The elder rejoices that some of the children are already walking in truth. He does not invent a new command. He simply recalls the one they have had from the beginning: love one another. Love is defined as walking according to the commandments already given. In the New Covenant the law is written on the heart; the call is not to discover something novel but to continue in what has been received.
Many deceivers have already gone out. Their defining mark is the refusal to confess that Jesus Christ came in the flesh. This is not a minor doctrinal difference. It strikes at the heart of the gospel. The one who does not remain in the teaching of Christ does not have God. The one who remains has both the Father and the Son. The issue is not progressive understanding; it is fidelity to the incarnation already accomplished and already proclaimed.
If a teacher arrives without this teaching, he is not to be received into the house or welcomed. To welcome such a one is to participate in his evil deeds. The New Covenant community is marked by love, but that love does not erase the boundary between truth and its denial. Hospitality serves the truth; it does not replace it.
The elder prefers presence over paper. He hopes to speak face to face so that joy may be made full. The letter ends with ordinary greetings from the children of the chosen sister. Even in a short warning letter, the ordinary life of the household of God continues.
The truth remains. The command to love is already given. The confession that Jesus Christ came in the flesh is the settled centre. We do not wait for a future delivery of these things. We remain in what has already been given. Remaining is the ordinary posture of those who live in the finished work of Christ.
Where are you tempted to treat as optional what the elder treats as non-negotiable — the incarnation, the original commandment of love, or the boundary of fellowship around the teaching of Christ?
