A Wolf found great difficulty in getting at the sheep owing to the vigilance of the shepherd and his dogs. But one day it found the skin of a sheep that had been flayed and thrown aside, so it put it on over its own pelt and strolled down among the sheep. The Lamb that belonged to the sheep, whose skin the Wolf was wearing, began to follow the Wolf in the Sheep’s clothing; so, leading the Lamb a little apart, he soon made a meal off her, and for some time he succeeded in deceiving the sheep, and enjoying hearty meals. “APPEARANCES ARE DECEPTIVE” (Reference: Aesop’s Fables).

The Bible counsels us to be aware and beware of false prophets in our midst. Jesus called these false prophets, ravening wolves in sheep’s clothing (Matthew 7:15). Unfortunately, many a times, many of us get carried away by the gifts that people have, instead of recognizing them for their fruits (Matthew 7:16). Those who are filled with the Holy Spirit of God, will have the fruit of the Spirit, which is love, joy, peace, longsuffering, gentleness, goodness, faith, meekness and temperance evident and expressed in and through their life (Galatians 5:22) and we are to try each spirit to see if it is from God and believe not every spirit, because many false prophets have come into this world (1 John 4:1). And every spirit that confesseth not that Jesus Christ is God who had come in the flesh is the spirit of the antichrist and that includes any people/groups that may seem like they are Christian (e.g., Jehovah’s witness), but inwardly are ravenous wolves. Appearances that claimed not Jesus is the Christ is deceptive.

Matthew 7:15-17 (KJV)
15 Beware of false prophets, which come to you in sheep’s clothing, but inwardly they are ravening wolves.
16 Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?
17 Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit.
18 A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit.
19 Every tree that bringeth not forth good fruit is hewn down, and cast into the fire.
20 Wherefore by their fruits ye shall know them.

1 John 4:1-3 (KJV)
Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
Hereby know ye the Spirit of God: Every spirit that confesseth that Jesus Christ is come in the flesh is of God
And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist, whereof ye have heard that it should come; and even now already is it in the world.
