I disagree with you on this, and believe there is good evidence for a contrary view, but I also think it's the kind of thing believers should be able to discuss politely.
Kinda hard to be polite all the time when some folks are trying to get others to believe teaching that comes from the devil
God's Word foretold that in the end times deception would be the greatest danger (Math 24) and that there would be many false teachers spreading false doctrine:
Matthew 24:4,5
And Jesus answered and said unto them, Take heed that no man deceive you.
For many shall come in my name, saying, I am Christ; and shall deceive many.
*Includes many claiming "I am anointed" deceiving many (false teachers)
1 Timothy 4:1,2
Now the Spirit speaks expressly, that in the latter times some shall depart from the faith,
giving heed to seducing spirits, and doctrines of devils;
Speaking lies in hypocrisy; having their conscience seared with a hot iron
("depart from the faith" is not referring to sinners in the world who never came to faith in the first place)
1 Timothy 6:3-5 (see Luke 11:23 and 2 Peter 3:2)
If any man teach otherwise, and consent not to wholesome words,
even the words of our Lord Jesus Christ, and to
the doctrine which is according to godliness (holiness);
(Doctrine of Christ, aka Doctrine of the Apostles)
He is proud, knowing nothing, but doting about questions and strifes of words, whereof comes envy, strife, railings, evil thoughts… Perverse disputings of men of corrupt minds, and destitute of the truth, supposing that gain is godliness: from such withdraw thyself.
2 Timothy 4:3,4
For the time will come when they will not endure sound doctrine (teaching); but after their own lusts shall
they heap to themselves teachers, having itching ears;
And
they shall turn away their ears from the truth, and shall be turned unto fables.
2 Peter 2:1-3
But there were false prophets also among the people, even as
there shall be false teachers among you, who privily shall bring in damnable heresies,
even denying (contradicting, Not agreeing with) the Lord that bought them, and bring upon themselves swift destruction.
And many shall follow their pernicious ways; by reason of whom
the way of truth shall be evil spoken of.
And through covetousness (idolatry) shall they
with feigned words make merchandise of you: whose judgment now of a long time lingers not, and their damnation slumbers not.
Jude 1:4
For there are certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men,
turning the grace of our God into lasciviousness (no self control, living after the flesh), and denying (contradicting, opposing Jesus’ teachings) the only Lord God, and our Lord Jesus Christ. (
referring to false teachers and false brethren - see Matthew 13:24-30)
(Deny = Strong's G0720… to contradict, disavow, reject, deny, refuse - and Strong's G4483… the idea of pouring forth, to utter, speak of or say, command)
Jude 1:17-21
Remember the words which were spoken before of the apostles of our Lord Jesus Christ;
How that they told you
there should be mockers in the last time, who should walk after their own ungodly lusts.
These are those who separate themselves, sensual, having not the Spirit.
But you, beloved, building up yourselves on your most holy faith, praying in the Holy Ghost,
Keep yourselves in the love of God, looking for the mercy of our Lord Jesus Christ unto eternal life.
("those who separate themselves" is not referring to sinners in the world who were never joined unto the Lord in the first place)
Acts 20:27-30
For I have not shunned to declare unto you all the counsel of God.
Take heed therefore unto yourselves, and to all the flock, over which the Holy Ghost hath made you overseers, to feed the church of God, which he hath purchased with his own blood.
For I know this, that
after my departing shall grievous wolves enter in among you, not sparing the flock.
Also
of your own selves shall men arise, speaking perverse things, to draw away disciples after them.
