Testing the Spirits¶

The text. "Beloved, do not believe every spirit, but test the spirits to see whether they are from God, for many false prophets have gone out into the world. By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God." (1 John 4:1-2, ESV)

"Do not quench the Spirit. Do not despise prophecies, but test everything; hold fast what is good." (1 Thessalonians 5:19-21)

The command to test¶

Testing is not the opposite of faith; it is a command. John's "test the spirits" is a present imperative addressed to a beloved congregation, not to experts. Paul puts the duty in a sentence that guards both errors at once: "Do not despise prophecies, but test everything." Contempt and credulity are the two ways to fail, and the verse forbids both in one breath. A church that accepts every word is disobedient; so is a church that has quietly decided there is nothing to weigh.

The setting is the assembly: "Let two or three prophets speak, and let the others weigh what is said" (1 Corinthians 14:29). The Spirit who gives the word also gives the church the judgment to test it.

The tests Scripture gives¶

Scripture does not leave us with a feeling. It gives tests, and they are embarrassingly ordinary.

Deuteronomy 13 gives the hard case: a sign or wonder that actually comes to pass, and a message that leads away from the Lord. "You shall not listen to the words of that prophet" (13:3). A true miracle does not validate a false message. Deuteronomy 18 gives the other test: "if the word does not come to pass or come true, that is a word that the LORD has not spoken" (18:22). Jesus adds fruit (Matthew 7:16), Paul the christological confession (1 Corinthians 12:3), John the incarnation (1 John 4:2).

One warning before the protocol. In Acts 16 a slave girl with "a spirit of divination" follows Paul and cries, "These men are servants of the Most High God, who proclaim to you the way of salvation" (16:17). Every word of that is true, and it is still an unclean spirit. Accuracy alone is not the test.

A practical protocol¶

1. The doctrinal test: who is Jesus?¶

Does the word confess Jesus Christ come in the flesh, and Jesus as Lord? "No one can say 'Jesus is Lord' except in the Holy Spirit" (1 Corinthians 12:3). A prophecy that diminishes Christ, adds to him, or relocates him has failed at the first gate.

2. The gospel test: does it lead to the apostolic gospel?¶

A word may be accurate in detail and wrong in direction. "Even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed" (Galatians 1:8). Ask where it takes you: toward repentance and the Christ of the apostles, or toward a new revelation and a new elite.

3. The fruit test: character, money, family, victims¶

"You will recognize them by their fruits" (Matthew 7:16). Look at the life, slowly. Does the money flow to the minister or the poor? Does the family hold together? Are there casualties — people used, discarded, or sworn to secrecy? False teachers "in their greed... will exploit you with false words" (2 Peter 2:3). A life systematically crooked is a reason to stop listening, not to listen harder.

4. The truth test: did it come true, and how was it given?¶

The test of Deuteronomy 18 still stands: write down what was said; vagueness is a way of never being wrong. Ask how it was given: "the spirits of prophets are subject to prophets" (1 Corinthians 14:32), so a word that leaves the speaker out of control, or must be delivered without question, has failed a test the text supplies.

5. The edification test: does it build up?¶

"the one who prophesies speaks to people for their upbuilding and encouragement and consolation" (1 Corinthians 14:3). Not flattery, and not a wounding "word" delivered as though the Lord were cruel. Ask whether the effect is faith and comfort, or fear and dependence on the prophet.

6. The accountability test: is the prophet under authority?¶

"Let the others weigh" assumes a prophet will submit his words to be weighed. Paul says a genuine prophet will "acknowledge that the things I am writing to you are a command of the Lord" (1 Corinthians 14:37). A ministry that answers to no one and cannot be corrected is not to be trusted, whatever its results.

When a word fails¶

It will happen, and how it is handled matters more than the failure.

Name it. Do not spiritualise it into vagueness ("the Lord meant something else"), and do not reflexively claim it was conditional; that defence can become a way of never being wrong. Distinguish the possibilities honestly. A word may have come out of the speaker's own heart: "They speak visions of their own minds, not from the mouth of the LORD" (Jeremiah 23:16). It may have been true but partial, since "we prophesy in part" (1 Corinthians 13:9). It may have been conditional, as Jonah's word to Nineveh was (Jonah 3:4-10). Or the time may not yet have come: "If it seems slow, wait for it" (Habakkuk 2:3).

Then act. If it was public, correct it publicly. Apologise without excuses. If the person will not be corrected, they are not ready to be listened to. But do not let one failure produce the other error: "Do not despise prophecies" (1 Thessalonians 5:20). The remedy for bad prophecy is better testing, not silence.

Testing a healing claim¶

The same discipline applies to healing, and it is mostly a matter of not saying more than you can attest. Separate the diagnosis from the change: what was wrong, on whose authority, and what is different now? Ask when it changed, who examined it, whether it has lasted, and whether ordinary means explain it. Report at the level of the evidence — "she says the pain has gone" is honest; "God cured her cancer" may not be. Never tell anyone to stop medication. The tests for weighing testimony in general are set out in how to weigh a testimony, and the reckoning with fraud in why so much of it is fake.

What this does and does not prove¶

It proves: that testing is commanded, that Scripture supplies concrete tests, and that a church can obey both "test everything" and "do not despise prophecies" at once.

It does not prove: that testing makes the church safe, or that a word which passes every test is infallible. Tests filter; they do not canonise.
