As a Christian and a preacher/teacher, I am frequently teaching people how different cults or world religions differ from Christianity and biblical teaching. In doing so, I have to point out what’s wrong with these other belief systems, how they contradict the Bible, how they go against the evidence, why they are untrue and even demonically inspired. I consider this to be part of my calling. You can’t just proclaim the truth; it’s also necessary to compare and contrast it with anything untrue.
