Passage
Beloved, believe not every spirit, but prove the spirits, if they are of God; because many false prophets are gone out into the world.
Beloved, believe not every spirit, but prove the spirits, if they are of God; because many false prophets are gone out into the world.
1 John 4:1 Beloved, believe not every spirit, but prove the spirits, if they are of God; because many false prophets are gone out into the world.
1 John 4:2 Hereby ye know the Spirit of God: every spirit which confesses Jesus Christ come in flesh is of God;
1 John 4:3 and every spirit which does not confess Jesus Christ come in flesh is not of God: and this is that [power] of the antichrist, [of] which ye have heard that it comes, and now it is already in the world.
The verse centers on "Spirit", "world", "beloved", "believe", "prove", "spirits", "false", and "prophets". It is saying that the verse draws attention to "Spirit" and "world", so its meaning should be read from those terms before moving to application.
The next verse adds "Hereby ye know the Spirit of God...", so "Spirit" and "world" should be read forward into that movement. 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 "world" with trust shaped by these words, not by a vague optimism outside the passage.
