“It is an easy thing to be godly from the teeth outward.”
Preceeding quote is from Matthew Henry’s (1710 AD) comments describing false teachers in Romans 16:18.
One godly characteristic the false teachers exhibited was “Christian” speech. From the teeth outward they appeared godly. In other words, they used Christian lingo and profess to be Christian but inwardly, in their heart, they are ravenous wolves sent by satan to mislead the true born again Christians. They use their oratory skills and cunning to lead Christians astray. The scripture says
“… and by their smooth and flattering speech they deceive the hearts of the unsuspecting.” (Romans 16:18)
The Lord Jesus warned about these people:
“Beware of the false prophets, who come to you in sheep’s clothing, but inwardly are ravenous wolves.  You will know them by their fruits. Grapes are not gathered from thorn bushes nor figs from thistles, are they?  So every good tree bears good fruit, but the bad tree bears bad fruit.  A good tree cannot produce bad fruit, nor can a bad tree produce good fruit.  Every tree that does not bear good fruit is cut down and thrown into the fire.  So then, you will know them by their fruits. …. (Matthew 7: 15-20)
Don’t be “unsuspecting” but be a fruit inspector. The Lord Jesus is telling you and me that by examining the fruit of their lives you can recognize the ravenous wolves despite their Christian words, mannerisms, associations, and their smooth and flattering speech.
In another blog we will discuss some of the fruit you should look for.
THEREFORE, “Gird your minds for action, keep sober in spirit” (I Peter 1:13) and “be on alert, your adversary, the devil, prowls about…seeking someone to devour” (I Peter 5:8).
