Further in the scripture we see that Joseph still feeds his brothers. Regardless of how we feel about those we journey through life with do we still choose to do what Jesus would do? Notice Joseph's father grieves for him. Joseph's father grieves for what happened to his son. In all ways Jesus knows how we feel. Jesus get's it. Jesus has been through it.
We live knowing the truths of the New Testament. Joseph didn't have this revelation. Yet Joseph passed the test. What do we do when we are wronged by a stranger is one thing. Being wronged by a brother, let alone several brothers who gang up against us and lie about it is another story.
I feel that the Body of Christ is in this story right now. The Body of Christ at large is at the place of choice. What decisions will we make because of how we have been treated? These decisions will reveal who are Daddy is.
