This teacher demonstrates a consistent pattern of pseudo-Christian teaching that lacks important biblical balance, overemphasizing some truths at the complete expense of others. Also, this teacher consistently mishandles scripture, disregarding the broader context of each verse as well as the systematic and historic understanding of each biblical doctrine. It is common for a Dangerous Teacher to look the part to many, but to consistently teach half-truths and lies, because he (or she) unwittingly lacks the wisdom of The Spirit to personally understand Scripture. Therefore, they should not be teachers.
Whether for the influence of popularity, the status of drawing a crow or financial gain, Dangerous Teachers will say things people want to hear in a way they want to hear them – all while appealing to more human-centered and worldly desires. While their lifestyle is often in question, you need not look any farther than their teaching to discern they regularly teach error mixed with a minimum amount of truth in order to perpetuate their agenda. So many of these teachers are effective because of how sincere they are, due to the fact that they are themselves sincerely deceived. This sincerity does not excuse their deception.
While it is theoretically possible, this teacher is most likely not a true believer. These teachers are dangerous because they give people a false sense of spirituality by inspiring belief in a God that does not really exist, and is not the God of the Bible.
Many Irresponsible & Dangerous Teachers are highly pragmatic. That is to say they despise the clear instruction of the Bible and deny the power of Christ to grow His Church how and when He decides to do it, and they over-emphasize human efforts to achieve measurable outcomes, namely numerical growth and money.
You will notice that Irresponsible, Dangerous, & False Teachers rarely, if ever, mention discernment unless it is to discourage it. Many of these teachers would rather preach unity ("unity" despite doctrine) either so their teaching is no longer criticized, or increase their influence and listenership.
Most Dangerous will profess to hear directly from God regarding either what to teach on or the direction of their ministry. They use this divine revelation to cast vision for everything from their church to their country. By doing this, they reject the sufficiency of Scripture.
Irresponsible, Dangerous, & False Teachers will be those who permit women to be "pastors." Scripture prohibits women from exercising authority in the church and are, by God's design, not qualified to be pastors in the church.
Most Irresponsible, Dangerous, & False Teachers will freely use multiple translations or "versions" (even paraphrases) during a single sermon. This typically means they are looking for verses that help them say what they want to say. While pointing out the nuances of translation from various sources can certainly be helpful, these teachers are motivated not by teaching what the Bible means, but by proof-texting their message's main points.
Do not critique a teacher on the basis of individual sermons. Even heretical teachers say Biblically accurate things. And its possible they preach an entire sermon without denying historical Christian truths or severely distorting Scripture. It is unlikely, however it is possible. Frankly, this is the reason many Dangerous & False Teachers remain influential; most Christians feel bad making a judgment despite a traceable pattern of error and end up excusing and ultimately endorsing false teaching.
Most Dangerous & False Teachers frequently engage in the blasphemous practice of what is called "Eisegesis." By exchanging the preposition Ex at the front of the word Exegesis (which means to take out) with Eis, we get the word Eisegesis (which means to put IN). Eisegesis, then, is the process of "putting into" the text one's own presuppositions, feelings, desires, agendas, etc. While this approach to the Bible may appeal more to our interests, particularly those of lost people, the job of the pastor is to preach the Word and explain its meaning. A faithful teacher will exegete, or pull out of text what God is saying in His Word. A fundamental truth about the Bible is it is not about us. It is about God. And while it is "to" mankind and it includes us, it remains God's Word about Himself and how we are to respond.
Dangerous & False Teachers will likely subscribe to and/or teach the unbiblical "Dream/Destiny" Doctrine. This false doctrine is a self-absorbed, purpose-driven emphasis comes from an abusive misinterpretation of the Bible and teaches people to use God and His promises to achieve the calling, dream, or destiny that God has supposedly given them.
1 Timothy 1:3-11 - As I urged you when I was going to Macedonia, remain at Ephesus so that you may charge certain persons not to teach any different doctrine, nor to devote themselves to myths and endless genealogies, which promote speculations rather than the stewardship from God that is by faith. The aim of our charge is love that issues from a pure heart and a good conscience and a sincere faith. Certain persons, by swerving from these, have wandered away into vain discussion, desiring to be teachers of the law, without understanding either what they are saying or the things about which they make confident assertions. Now we know that the law is good, if one uses it lawfully, understanding this, that the law is not laid down for the just but for the lawless and disobedient, for the ungodly and sinners, for the unholy and profane, for those who strike their fathers and mothers, for murderers, the sexually immoral, men who practice homosexuality, enslavers, liars, perjurers, and whatever else is contrary to sound doctrine, in accordance with the gospel of the glory of the blessed God with which I have been entrusted.
3 John 9-10 - I have written something to the church, but Diotrephes, who likes to put himself first, does not acknowledge our authority. So if I come, I will bring up what he is doing, talking wicked nonsense against us. And not content with that, he refuses to welcome the brothers, and also stops those who want to and puts them out of the church.
Titus 1:11 - They must be silenced, since they are upsetting whole families by teaching for shameful gain what they ought not to teach.
