One of the reasons 2 John was written was to warn about deceivers who deny that Jesus Christ came in the flesh. In order to understand what the author of 2 John was warning against, we need to understand what the Bible means by deceivers.

In this lesson I look at various verses in the New Testament that help us understand the concept of deception. We’re going to see two things. We’re going to see that in deception, the person who is deceiving others appears to be something that he is not. We're also going to see that deception is usually something that happens incrementally. When people are deceived, they generally do not go from truth to error in one big step. Instead, they incrementally move from truth to error.

After I look at the verses that explain the concept of deception, I'll come back to 2 John to see what you and I should learn from 2 John in regards to deceivers and Jesus Christ coming in the flesh.
