This document provides instructions for an object lesson where kids play spot the difference puzzles. It is explained that the lesson is meant to illustrate how sin is anything that does not match up to God's standard in the Bible. There are sins of omission, where something is left out that should be there, and sins of commission, where something is added that should not be. To identify mistakes in their own lives, kids are told to compare their lives to what is commanded or forbidden in the Bible.
