To some in the religious world it’s not a popular topic; but it’s not a topic that the Bible shies away from talking about. As a matter of fact, there’s not a single writer in the New Testament who didn’t warn about false teachers or false doctrine in one way or another.
Matthew, Mark, Luke, Paul, James, Peter, John and Jude all speak up, and they speak the same thing! Watch out for liars:
Coincidental warnings? I think not!
In a “Christendom” so full of confusion and conflicting stories and beliefs that have no basis in the scriptures the focus must be put on what Jesus and his apostles and prophets said through the light of God’s word. For therein is the safe path for our spiritual feet, and therein is the safe way to identify those who speak by any other spirit than God’s (Psalm 119:105, 2 Peter 1:19-21). It’s true – there’s such a thing as false teachers and false doctrine, and it’s the truth of God’s word that reveals it.
“Now the Spirit expressly says that in latter times some will depart from the faith, giving heed to deceiving spirits and doctrines of demons, speaking lies in hypocrisy, having their own conscience seared with a hot iron,” (1 Timothy 4:1-2)
