Remember Your Roots
This is where we learn about original sin and why we are so bad compared to God. We all have God's law written in our heart. It's like our conscience. When we do something that causes us to feel guilty or sends up a red flag in our heart, this is a sin. Everyone sins. We have this other little voice that justifies sinning. That is Satan.
Anyway, this story explains why we all sin and why we all need to be saved in able to speak with God like we're supposed to.

Genesis 3:1-4 and Genesis 3:6-8
