Ahead of Sunday you might want to read Genesis 3, and think about the tactics the devil used to tempt Adam and Eve to sin, and then the consequences of sin in their lives. Nothing much has changed since the days of Adam and Eve - what was true for them is true for us too, and there is much we can learn from their experience.
If you have time you might also want to head over into Genesis 4, and consider the question God asks Cain - “Where is your brother Abel?”. Take a moment to ponder why God might ask a question He already knows the answer to!
It's going to be really good on Sunday. We've got a great drama to support the preach - come expecting God to speak to you and challenge you.
