When answering questions about the Gospel or working with people who disagree with us in good faith, we must give reasons for our position with gentleness. In fact, this must be our default position. Yet if we encounter false teachers who deny Christ, prey on others, live for greedy gain, and refuse to change, then we must use strong words to show the severity of this evil and to protect others from false teachers. Therefore, while reasoned gentleness should be our default stance, we should not shrink from using strong language when necessary. And I think strong language is necessary to use when dealing with the following groups of people.
