1 John 4:1 gives us a very important task and it's important to understand the context of the solution it presents.
THE TASK:
"1 Dear friends, do not believe everyone who claims to speak by the Spirit. You must test them to see if the spirit they have comes from God. For there are many false prophets in the world."
THE SOLUTION:
"2 This is how we know if they have the Spirit of God: If a person claiming to be a prophet acknowledges that Jesus Christ came in a real body, that person has the Spirit of God. 3 But if someone claims to be a prophet and does not acknowledge the truth about Jesus, that person is not from God. Such a person has the spirit of the Antichrist, which you heard is coming into the world and indeed is already here."
This passage specifically calls out prophets. But let's say it applies to anyone who is "prophetic". Is this the ONLY test? Choose below the most RELIABLE source for testing them OTHER THAN if they can confess Yeshua/Jesus came in the Flesh.
The context of this passage was aimed at the Gnostics who taught Adoptionism and what is now called the Christ Principle. Both are doctrines current making a very popular reappearance.
So what if someone is NOT a Gnostic, but has shown tendencies toward the "prophetic". Choose which answer below is the most reliable means of testing the spirit they are prophesying from.
