First John Chapter 4:1-5
“It is important to observe that the command to believe on the name of God's Son Jesus Christ (3:23) is followed by a prohibition, believe not every spirit, much as the commandment to love (2:7-8) was followed by the prohibition, ‘love not the world’(2:15). Neither Christian faith nor Christian love is indiscriminate. In particular, Christian faith is not to be mistaken for credulity. True faith examines its object before reposing confidence in it” (Stott p. 152). 1John 4:1 “Beloved, believe not every spirit, but prove the spirits, whether they are of God; because many false prophets are gone out into the world” “Beloved”: This expression will occur three times in this chapter (4:1,7,11). We sometimes forget that serious teaching, admonition or rebuke can be more effective when accompanied by tender affection for those being warned. The truth can be taught effectively and ineffectively. Someone said that in hearing two different speakers talk about the subject of hell and teach the same truth, one speaker made it sound like he was glad I was going there, and the other sounded like it broke his heart that I was headed in that direction. “Believe not every Spirit”: “Stop believing” (Robertson p. 229). “Unbelief can be as much a mark of spiritual maturity as belief” (Stott p. 153). There are things in which the Christian must not believe. The Christian cannot be gullible (Mark 4:24 “Take care what you listen to”; Acts 17:11; 1 Thess. 5:21; 1 Tim. 6:3). True spirituality isn't believing every religious idea or theory. “Every Spirit”: Possibly those teaching the following false doctrine claimed to be inspired of God. “Refrain from believing every teacher who claims to be from God” (Woods p. 287). Behind every teacher there is a "spirit", i.e. the source of their teaching is either God (either direct revelation, or subject matter found in His written revelation), or the devil. Every teacher either preaches the truth or he is preaching error. Observe that preaching some truth doesn't make up for the error that one preaches. 1
