Help students understand what sin is in a non-threatening way, using this lesson to explain the concept of selfishness vs. selflessness.
First, students read a brief (original) essay explaining what it means to "point out" or "point in". Next, students answer reflective questions to ensure understanding of the text. Finally, work as a class (or in small groups or individually) to chart out what pointing in or out LOOKS like in modern day, listing examples of what is and is not sinful.
By the end of this lesson, students have a memorable way to understand what sin is and how to avoid it.
