Dear friends, do not believe every spirit. (1 John 4:1a)
It is quite true that a mark of maturity is unbelief as well as belief. It is as important that you do not believe certain things as it is that you do believe others. John indicates that this is a widespread problem.
Many false prophets, he says,
have gone out into the world (1 John 4:1a). In Matthew’s gospel, the Lord Jesus warned of this:
Watch out for false prophets. They come to you in sheep’s clothing, but inwardly they are ferocious wolves (Matthew 7:15). Here we have underlined for us the fact that we live in a world of deceit, and we are greatly pressured to conform to these things.
