Paul wrote that God appointed teachers in the church (Romans 12:7, I Cor 12:28). If you agree with him, do you think those preachers and other teachers who were appointed by God (never mind any others) never make any mistakes in what they preach and teach?
Paul also wrote this
”For the time will come when they will not endure sound doctrine; but wanting to have their ears tickled, they will accumulate for themselves teachers in accordance to their own desires, and will turn away their ears from the truth and will turn aside to myths.“
2 Timothy 4:3-4 NASB1995
And this
”For such men are false apostles, deceitful workers, disguising themselves as apostles of Christ. No wonder, for even Satan disguises himself as an angel of light. Therefore it is not surprising if his servants also disguise themselves as servants of righteousness, whose end will be according to their deeds.“
2 Corinthians 11:13-15 NASB1995
And this
”If anyone advocates a different doctrine and does not agree with sound words, those of our Lord Jesus Christ, and with the doctrine conforming to godliness, he is conceited and understands nothing; but he has a morbid interest in controversial questions and disputes about words, out of which arise envy, strife, abusive language, evil suspicions, and constant friction between men of depraved mind and deprived of the truth, who suppose that godliness is a means of gain.“
1 Timothy 6:3-5 NASB1995
And this
”I am amazed that you are so quickly deserting Him who called you by the grace of Christ, for a different gospel; which is really not another; only there are some who are disturbing you and want to distort the gospel of Christ. But even if we, or an angel from heaven, should preach to you a gospel contrary to what we have preached to you, he is to be accursed! As we have said before, so I say again now, if any man is preaching to you a gospel contrary to what you received, he is to be accursed!“
Galatians 1:6-9 NASB1995
Now according to all this did Paul actually teach that all preachers are chosen by God?
