The Joseph story is one of my favourites in scripture. It doesn't get much more real (except perhaps the cross!). A husband and his two wives ("And it was Leah!), favoured sons, bitter rivalry and envy, betrayal, forgiveness, conversion, and through and in all this God's presence.
I have posted some material before on Joseph. Check out this post on the conversion that Joseph leads his brothers to, and the way in which God's response to evil is not a moralistic separation of the good and bad, neither is God's response a gnostic ignoring of evil, but joining the story and putting the evil on a broader canvas of God's purposes. ("God intended it for good.") Or this post, a short reflection on how Christ is feels no envy toward us, and that through his Spirit we need not be envious of him, for everything that we can receive has been given to us.
