Genesis Chapter 3
In Genesis 3, we have Moses tracing for his Israelite readers the ultimate cause of the presence of suffering, hardships pain and death in the world. He shows that all these are the results and effects of disobeying God.
The purpose is to encourage obedience and discourage disobedience.
This chapter also highlights and emphasizes the threatened punishment stipulated in the Mosaic covenant of being driven out of the land of Promise if they disobey God. Just as Adam and Eve were driven out of Paradise, so will they be driven out of the Promise Land if they choose to live independently from God.
