Matthew 7:15 Beware of false prophets, who come to you in sheep’s clothing, but inwardly they are ravenous wolves.
16 You will know them by their fruits.
Jesus makes us aware of these false prophets, those who look and even talk like christians, but are not born again. They dont speak for God. We spot them out by their fruit or what they say and do. Does it line up with the word of God? Does it reflect the Persons of God? Talk is cheap. What about actions. These wolves are intentional in that they deliberately decieve folks. John gives us warning. Dont believe every spirit, test wheather they are of God or not. We have a wonderful litmus test for these, Jesus and His holy word.
