1 John 4:2 Hereby know ye the Spirit of God: every spirit that confesseth that Jesus Christ is come in the flesh is of God:

1 John 4:4 Ye are of God, [my] little children, and have overcome them: because greater is he that is in you than he that is in the world.

Study Lenses

The verse centers on "Spirit", "hereby", "confesseth", "jesus", "christ", "come", and "flesh". It is saying that the verse draws attention to "Spirit" and "hereby", so its meaning should be read from those terms before moving to application.

The nearby context moves from verse 1's "Beloved believe not every spirit but prove..." into verse 3's "and every spirit that confesseth not Jesus...", so "Spirit" and "hereby" belong inside that flow. In 1 John context, the local focus is Christ, faith, and discipleship.

A plain takeaway is to answer the verse's own emphasis on "Spirit" and "hereby" with trust shaped by these words, not by a vague optimism outside the passage.
