I was looking through my notes as I prepare to teach the Winter session in Warsaw, Poland in a couple of months. The session is “Biblical Doctrines” and the study that we will “tackle” in order to learn Biblical doctrines is “Covenant” written by Kay Arthur. As I was looking through my notes I decided to write a post on what the Bible has to say about the dangers of not knowing “sound doctrine”. The word “doctrine” comes from the Koine Greek word “didaskalia”and it means “teaching, instruction, precept, explanation”. Doctrine informs us of what God wants from us, what is right and wrong, and how we can live by God’s standards. There are terrible consequences to not knowing sound doctrine. I would like to present what the Bible has to say about the subject of not knowing “sound doctrine”.
