The point of Genesis 37-39 is the same point as the whole story of Joseph (chapters 37-50), that we should believe that God always accomplishes his sovereign plan for the good of those who love him. In the first three chapters of this epic, we see three powerful reasons why we should believe this: (1) the sin of hatred is not able to thwart the plan of God (ch. 37); (2) the sin of lust is not able to thwart the plan of God (ch. 38); and (3) the sin of deceit is not able to thwart the plan of God (ch. 39).
