What does 1 John 4:2 mean?
What is the meaning of 1 John 4:2?

By this you will know the Spirit of God

John sets out a simple, reliable measure for testing spiritual claims. God is not hiding the truth from His people; He wants us to discern.

• Jesus promised, “The Spirit of truth… you know Him, for He abides with you and will be in you” (John 14:17).

• The same Spirit “testifies with our spirit that we are God’s children” (Romans 8:16).

• Paul echoes the test: “No one speaking by the Spirit of God says, ‘Jesus be cursed,’ and no one can say, ‘Jesus is Lord,’ except by the Holy Spirit” (1 Corinthians 12:3).

Knowing is possible because the Spirit who inspired Scripture never contradicts Himself.


Every spirit that confesses

John moves from general discernment to a specific confession. “Confesses” is more than polite agreement; it is an open, heartfelt declaration.

• Jesus warned, “Whoever confesses Me before men, the Son of Man will also confess him before the angels of God” (Luke 12:8-9).

• True confession rises from belief that grips both mind and heart (Romans 10:9-10).

• False teachers may use Jesus’ name, but they avoid a clear, Scriptural confession; their silence or vagueness betrays them (Matthew 7:21-23).


That Jesus Christ has come in the flesh

This is the core of Christian doctrine: the eternal Son truly became human.

• “The Word became flesh and dwelt among us” (John 1:14).

• “Since the children have flesh and blood, He too shared in their humanity” (Hebrews 2:14).

• John warns again, “Many deceivers… do not confess Jesus Christ as coming in the flesh. Such a one is the deceiver and the antichrist” (2 John 7).

The incarnation secures our redemption; deny it and you unravel the gospel itself.


Is from God

A spirit—or teacher—who affirms the biblical Jesus stands under God’s authority.

• “Whoever is of God listens to God’s words” (John 8:47).

• “The one who keeps His commandments remains in Him, and He in him. And by this we know that He abides in us: by the Spirit He has given us” (1 John 3:24).

Right confession and right origin go together; orthodoxy and a genuine relationship with God cannot be separated.


summary

John provides a clear litmus test: acknowledge the real, incarnate Jesus and you reveal the Spirit of God at work. Reject or redefine Him and you expose a counterfeit spirit. Hold fast to the plain teaching of Scripture, and you will stand secure in the truth.
