Abounding in Christ's Love (Philippians 1:9-11)

When Joseph’s father dies his brothers are concerned about what will happen to them. They sold their brother Joseph into slavery, lied about their actions, and are a cause for Joseph’s hard days in Egypt. So, now that Joseph rises to power what will he do without their father to stand in the way? Why would Joseph let them get away with such horrible actions? Or does Joseph see something that Paul sees while Paul waits for his appeal to Caesar?
