1 John 2:18-23

Antichrists, the Last Hour, and the Denial of the Son

The presence of antichrists who depart from the apostolic fellowship and deny Jesus as the Christ reveals that it is the last hour and exposes the decisive importance of confessing the Son.

Scripture Text

2:18 Children, it is the last hour; and just as you have heard that the antichrist is coming, so now many antichrists have appeared. This is how we know it is the last hour.

2:19 They went out from us, but they did not belong to us. For if they had belonged to us, they would have remained with us. But their departure made it clear that none of them belonged to us.

2:20 You, however, have an anointing from the Holy One, and all of you know the truth.

2:21 I have not written to you because you lack knowledge of the truth, but because you have it, and because no lie comes from the truth.

2:22 Who is the liar, if it is not the one who denies that Jesus is the Christ? This is the antichrist, who denies the Father and the Son.

2:23 Whoever denies the Son does not have the Father, but whoever confesses the Son has the Father as well.

Anchor

The presence of antichrists who depart from the apostolic fellowship and deny Jesus as the Christ reveals that it is the last hour and exposes the decisive importance of confessing the Son.

Those who abandon apostolic doctrine and deny that Jesus is the Christ reveal that they do not truly belong to the fellowship, for denying the Son is inseparable from rejecting the Father.

Point of Contact

To comfort believers who sin, confront false claims of knowing God without obedience, warn against worldliness, and strengthen the church to abide in the apostolic confession of the Son.

Rhythm

  1. Gospel Provision The chapter begins with the believer’s provision in Christ: advocacy before the Father and atonement for sins.
  2. Obedience Test John tests claims to know God by obedience to God’s commands and imitation of Christ’s walk.
  3. Love Test John tests claims to be in the light by love for fellow believers and rejection of hatred.
  4. Family Assurance John pauses to reassure the church that they truly know God, are forgiven, and have overcome the evil one.
  5. Worldliness Warning John warns against love for the passing world and calls believers to do the will of God.
  6. Christological Discernment John exposes antichrist deception as denial of the Son and departure from apostolic fellowship.
  7. Abiding Exhortation John calls believers to remain in what they heard from the beginning and continue in Christ until his appearing.

Crucial Turning Point

The chapter moves from Christ’s advocacy for sinners to the evidences of genuine knowledge of God: obedience, love, rejection of the world, discernment of antichrist denial, and abiding in the Son.

John argues that the believer’s assurance rests in Christ’s righteous advocacy and atoning work, but that genuine knowledge of God is evidenced by obedience, love, separation from the world, confession of the Son, and perseverance in the apostolic truth.

Theological logic
  1. Believers must not treat sin lightly, yet sinners have an advocate in Jesus Christ the righteous.
  2. Knowing God is tested by obedience.
  3. Walking in the light is tested by love.
  4. The church should receive assurance without relaxing vigilance.
  5. Love for the world is incompatible with love for the Father.
  6. Christological denial reveals antichrist deception.
  7. Believers must abide in the message heard from the beginning.
  8. Continuing in Christ prepares believers for confidence at his appearing.

Watch Out

  • Misreading: Antichrist refers only to a single future political figure. Correction: John explicitly states that many antichrists are already present, indicating an ongoing spirit of opposition centered on denying Christ.
  • Misreading: Anyone who leaves a local church proves they were never saved. Correction: John addresses departure rooted in doctrinal denial of Christ, not ordinary relocation or secondary disagreements.
  • Misreading: The anointing eliminates the need for teaching or discernment. Correction: John himself teaches and warns, showing that the Spirit’s anointing works through faithful apostolic instruction, not apart from it.
  • Restricting antichrist to a single future individual only. John describes multiple present opponents characterized by denial of Jesus as the Christ.
  • Interpreting anointing as private revelation beyond Scripture. The anointing confirms apostolic truth rather than introducing new doctrine.
  • Equating every disagreement with antichrist spirit. John specifies denial of Jesus as the Christ as the defining criterion.

Invitation Arc

Response
  • Confess sin quickly while consciously resting in Jesus Christ the righteous as advocate.
  • Examine claims to know God by concrete obedience rather than spiritual vocabulary alone.
  • Identify any hatred, bitterness, or lovelessness that contradicts walking in the light.
  • Name specific desires of the world that compete with love for the Father.
  • Review the apostolic confession of the Son and reject vague spirituality that minimizes Christ.
  • Practice abiding by returning daily to what was heard from the beginning: the gospel of Jesus Christ.
  • Live each day with the appearing of Christ in view.

Formation Aim

A steady, obedient, loving, discerning, Christ-abiding believer who rejects the passing world and waits confidently for Christ’s appearing.

Canonical Thread

Gospel Clarity

Jesus is the Christ, the promised Messiah and eternal Son of God. To confess Him rightly is to have the Father; to deny Him is to remain outside the life of God. Eternal life is bound to a true confession of the Son as revealed in the apostolic gospel.
