Why Expose False Teachers?
1 John 4:1
Beloved, believe not every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world.
2 Corinthians 11:4
For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him.
2 Timothy 3:13
But evil men and seducers shall wax worse and worse, deceiving, and being deceived.
I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel:
Which is not another; but there be some that trouble you, and would pervert the gospel of Christ.
2 Peter 2:1
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 the Lord that bought them, and bring upon themselves swift destruction.
Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned; and avoid them.
For they that are such serve not our Lord Jesus Christ, but their own belly; and by good words and fair speeches deceive the hearts of the simple.
I know thy works, and thy labour, and thy patience, and how thou canst not bear them which are evil: and thou hast tried them which say they are apostles, and are not, and hast found them liars:
And hast borne, and hast patience, and for my name’s sake hast laboured, and hast not fainted.
