The darkness of Achan's story heightens the glory of the gospel. The sin that Achan committed underscores the salvation that God offers. The cult he bore reveals the grace that is offered to us. Of Grace and Guilt is written to help us understand this reality. It is written to underscore the darkness of sin and therefore to examine the light of salvation. It is written for us to see the gracious hands of a loving God offered to us. The question before us is whether or not we will take what Achan could not.
