1. Good and Evil are equal forces
True - God is in control and uses the devil as a punishing rod upon the rebellious (Isa.10).
2. Our Free Will is a result of the Fall
Our free will comes from how God gave man free will, as He did with the angels also, otherwise even the cherub Satan could not have rebelled against Him. God creeated us to give Him pleasure, as in all things He originally created.
3. Knowledge of correct doctrine saves.
Not an error in thought. Doctrine involves principles of one's belief, a foundation. The Bible gives examples and teachings of the correct Doctrine unto Salvation, as written by God through His holy prophets and Apostles. Knowledge is not a negative word as some imply. Knowledge leads to understanding, and then by understanding leads to Faith and good works.
4. Thoughts or feelings can damn you
Not an error in thinking. The type of thoughts and feelings (emotions) one choses to entertain can and will influence their works and in what they chose to believe. This principle is often associated with how one's heart is in many Bible examples. As our Lord Jesus showed, where a man's heart is, that's where his treasure will be.
5. Being convinced of the truth and being converted mean the same thing
Not an error in thinking. Anyone believing on Christ Jesus must first be convinced of the Truth that He died on the cross for the remission of the sins of those who believe. One must be convinced of the witness of His Apostles that He died on the cross and rose the third day. That conviction is of the heart and mind of the believer. So conviction and conversion go hand in hand.
6. Christians can argue people into the Kingdom
The word 'argue' is not a negative term in itself. It's a word to show what one believes. Apostle Paul argued with the non-believers at Mars Hill, even quoting principles of their own philosophers to present the 'argument' of Who God really is. Presenting such arguments in order to bring the unsaved to Christ is just and necessary. When Elijah gave a challenge to the false prophets of Baal to find out who The God really is, he was posing an argument to them. This is why God's Word is for correction and reproof also to reveal the difference between righteousness and wickedness.
7, Witnessing doctrine is the same thing as love,
Not an error in thinking. Witnessing The Gospel of Jesus Christ IS witnessing Doctrine, specifically the Doctrine of Salvation through Jesus Christ. It IS an act of love to do that with the unbeliever.
8. Christians cannot be arrogant
All peoples can be arrogant at times, for that's about emotions. But many mistake the boldness of Christian witnesses in preaching Christ's Salvation and Biblical Truth for arrogance, especially when God's Word convicts a sinner in giving a rebuke.
9. The gospel must be offensive to the world or it is too watered down
Not an error in thinking, for both are true. The Gospel of Jesus Christ is offensive to the majority of those who refuse Christ Jesus and instead follow the ways of this world. Christ never claimed to bring peace within this present world, but instead a sword. Likewise, The Gospel is watered down by some who are like a reed shaking in the wind.
10. Every time a Christian is criticized it is a direct result of the gospel, rather than their behavior
Sometimes Christians are critizied simply because they believe The Gospel of Jesus Christ, and especially because of their behaviour when such behaviour is in preaching Christ crucified. It would be silly to deny that, especially since there are many Bible witnesses to that fact.
11. The Bible must be literally true or it is not valuable.
Either The Bible is literally True, or it is not the Truth. Can't be both ways. Even when God's Word uses expressions, allegory, and metaphor or parable, those are simply methods to show literal Truths.
12. The most important concept the Bible has to offer is literal truth
Not an error in thinking. Once again, if The Bible is not literal Truth, then what is it? It is certainly not just a book of poetry, nor man's philosophy. It is God's Letter to us as given through His holy prophets and Apostles. It is not of man, but divinely given through man by The Holy Spirit.
13. The OT is a series of stories about good people doing good things, who should be emulated, rather than a cautionary tale for humanity.
The OT is about history to include examples of man's behaviour in relationship with God, and against God when in rebellion. It is a lesson guide for right action and thinking, where those in Faith in OT times should be seen as setting good examples for us (Hebrews 11). There's good examples to follow, and examples of what NOT to follow. But they were not just stories. The OT events actually happenned.
14. Our behavior can change the wrath of God outlined in the book of Revelation and Daniel.
Not really an error in thinking. For IF all men repented today and came to The Father through The Son, leaving sin, His wrath would not come. But through His Word we already know not everyone is going to repent, and thus His hand is still stretched out in preparation to bring His wrath.
15. A literal interpretation of the Creation story is necessary in order to believe in a literal translation of the Bible, which is necessary to believe in a literal understanding of Christ and our possible Redemption.
Understanding specifically 'how' God created the heavens and the earth is not a Salvation issue. But understanding it does open other areas of His Word in a deeper understanding that many struggle with. Like Christ told His Apostles, it was given for them to know the mysteries of the kingdom of heaven, but for others it is not given. Those given to know will know.
16. People who reject the message of Christianity are our enemies.
Valid thinking error. Not everyone who refuses Christ is our literal enemy. But even they... will stand in judgment before Christ and give account.
17. The Devil is omnipresent
Valid thinking error. The devil is not omnipresent. God is in control.
18 God desires us to be destroyed rather than saved.
Truly an error in thinking. God desires for all men to come to repentance, and is long-sufferring.
19. God hates His enemies, but calls us to love our enemies.
God hates what the unjust do, as we should also. Showing discipline upon His enemies is not an act of hate.
20. Jesus only died for the elect.
Could be seen as an error of thinking, but He did die on the cross for His elect that were chosen before the foundation of the world (Eph.2). He died on the cross for all that would believe too. But not all will believe on Him.
21, Acknowledging a person's freedom to sin is the same as condoning it
NOT an error in thinking. Even allowing the open practice of a sin IS condoning the sin (Judges 19). This is especially so within Christ's Body, even while the unbelievers outside His Church are doing all sorts of abominations. There is to be a line of separation between His Church and this world involving sin. This is why Apostle Paul rebuked those in the Church for sin, as Christ did also with five Churches in Asia (Rev.2 & 3).
22. The ends justify the means
That definitely is an error in thinking. The 'end justifies the means' (i.e., reaching the desired end makes up for the evil done to get there) is a negative principle used by the secret societies, like Weishaupt's Illuminati order in 17th century Bavaria. God's people should follow the principle of 'the end is justified BY the means'.
23. We were kicked out of Eden for eating the fruit
That is an error in thinking. Adam and Eve disobeyed God's commandment is why they were expelled.
24. God can break His own rules
Depends on what is meant by "His own rules". God has had, and can have, a change of heart and hold off a punishment if His children repent and come back to Him. But His eternal law, He will not change, for it is immutable, and will exist for eternity.
25. Jesus was a conservative (I am not using this term in a political way)
Jesus told His Apostles to fish out of
the right side of the boat (I'm not using that in a political way either).
