The first description of a true Christian (i.e. a true follower of Jesus Christ) is that he or she has heard, understood, and believed in the Gospel (Acts 11:19-21, 26). But what is the true Gospel? There are many false versions of it circulating these days. Naturally, people are confused. In this lesson, we want to understand clearly what is the true Gospel so that we can at least say that we have heard and understood it clearly.
