The Hour of Deception and the Evidence of Remaining

Main Idea of 1 John (The Central Thesis):

1 John is a pastoral letter written to provide believers with absolute assurance of their salvation and fellowship with God. It serves as a definitive guide to distinguishing truth from error by applying the “tests” of sound doctrine, righteous living, and sacrificial love, all rooted in the historical reality of Jesus Christ.

The Logical Bridge (The Contextual Link):

Having just commanded believers not to love the world (2:15–17), John now identifies the specific way the world infiltrates the Church: through deception. He transitions from a warning against worldly desires to a warning against worldly doctrines. To remain in the light, the believer must recognize that the “last hour” is characterized by those who abandon the faith and deny the Son. Assurance is found in a faith that does not retreat from the Truth.

The Text: The Hour of Deception:

“Children, it is the last hour. And as you have heard that antichrist is coming, even now many antichrists have come. By this we know that it is the last hour. 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. However, they went out so that it might be made clear that none of them belongs to us.

But you have an anointing from the Holy One, and all of you know the truth. I have not written to you because you don’t know the truth, but because you do know it, and because no lie comes from the truth. Who is the liar, if not the one who denies that Jesus is the Christ? This one is the antichrist: the one who denies the Father and the Son. No one who denies the Son has the Father; he who confesses the Son has the Father as well.”

— 1 John 2:18–23 (CSB)

Observations (What the Text Says)

The Present Reality (v. 18): We are living in the “last hour,” evidenced by the arrival of many antichrists.

The Reveal of Apostasy (v. 19): A group of people departed from the apostolic teachings and community of believers, proving that their inward reality never matched their outward association.

The Spiritual Guardrail (vv. 20–21): Believers are equipped with an “anointing” from God that confirms the truth of the Gospel in their hearts.

The Litmus Test of Truth (vv. 22–23): The defining mark of the “liar” is the denial of Jesus as the Christ. Rejection of the Son reveals that there was never true fellowship with the Father.

Interpretation: The Tangible Truth (Understanding the Meaning)

The “Last Hour” and the Spirit of Antichrist (v. 18)

John identifies the time between Christ’s ascension and His return as the “last hour.” This era is marked by “antichrists”—those who oppose the true Gospel or offer a “counterfeit” Christ. Their presence is a fulfillment of what believers were told to expect.

The Common Error: True Apostasy vs. Church Transition (v. 19)

John says, “They went out from us, but they did not belong to us.” It is vital to apply this with biblical precision:

The Misuse/Abuse of the Text: Oftentimes, certain churches or leaders use this verse out of context to condemn anyone who leaves their specific local congregation. They imply that if you leave their church, you have left God. This inaccurate and is a spiritual abuse of the text often by incompetent teachers and/or men with impure intentions.

The Faithful Interpretation: John is not talking about people moving from one church to another. He is describing actual, full blown apostasy—people who completely abandon the faith, reject the Gospel, and deny the Lord Jesus Christ.

The Distinction: A believer might leave a local congregation for many valid reasons while still remaining “in the faith.” The people John describes left the body of Christ entirely. Their departure “made it clear” that they never possessed the life in Christ to begin with.

The Christological Test (vv. 22–23)

John identifies the “liar” as the one who denies that Jesus is the Christ.

The Inseparable Union: In biblical theology, the Son is the only way to the Father. Therefore, a rejection of the Son reveals that there never was fellowship with the Father through Him to begin with. 

The Evidence of Faith: You cannot claim a “private relationship” with God while redefining or rejecting Jesus. To have the Father, one must confess the Son; if the Son is denied, it proves the Father was never truly known.

Application (How We Respond)

Examine the Nature of Your Fellowship: Is your standing with God based on a confession of the biblical Jesus? Rejection of the Son’s deity or work is not a “minor error”; it is proof of a lack of fellowship with the Father.

Correct Misapplication: If you have been made to feel like an “apostate” simply for leaving a specific congregation, find peace. God’s test is not “Did you stay in that specific building?” but “Do you abide in the Son?”

Guard the Identity of Christ: Be wary of any teaching that minimizes Jesus. If a teaching contradicts the Truth about the Son, it reveals that the speaker does not have the Father.

Connection to the Main Idea

This text provides the doctrinal test of assurance. While the unregenerate eventually walk away from the Truth, the child of God is kept by the “anointing” of the Spirit and remains anchored in the confession of the Son.

How Does This Text Point to Christ?

Jesus is the Holy One who gives us the Spirit. While “many antichrists” arise, Jesus is the True Christ who holds His sheep fast. He is the only bridge to the Father; by confessing Him, we prove we are in fellowship with God.

Summary (Recap)

1 John 2:18–23 warns us that the “last hour” is a time of testing. Many will claim to be part of the community but will eventually prove they were not by abandoning the faith and denying Jesus. However, the true believer remains firmly rooted in the Son, which is the only evidence of having the Father.

Be Intentional (Putting it to Practice)

For Spiritual Health: Memorize verse 23. Let it settle the fact that your fellowship with the Father is found exclusively through your confession of the Son.

For Outreach: When sharing the Gospel, emphasize that God the Father cannot be known or worshiped apart from Jesus Christ the Son.

Ask Yourself (Personal Examination)

Does my confession of Jesus Christ reveal a true, ongoing fellowship with the Father?

Am I remaining in the Son, or am I just “clocking in” at a church?
