Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves. Matthew 7:15
While sight seeing the other day we saw what appeared to be a light house. When we got a little closer we realized it was a water tower made to look like a light house. It was quite elaborate. Even to the point of having fake windows every so often up the piping to the tank at the top.
Such it is wth false prophets; on the outside they walk, talk, and may even look like solid Christians. However, if you get a little closer and listen to what they are saying, you will notice real quick some things are missing from their message. What's that you ask? The fruit of the Spirit; "But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, Meekness, temperance: against such there is no law." Galatians 5:22-23
