While doing my Romans videos I happened to use a passage from Genesis about Joseph’s initial fulfillment of the Promise made to Abraham that blessing would come through his seed to the nations.
But what was I teaching about in Romans? I was teaching about how God was faithful to his promise to save the world through Abraham’s seed by using the unfaithfulness of Abraham’s seed.
And isn’t that exactly how Joseph was made “a father to Pharaoh”?
So Joseph said to his brothers, “Come near to me, please.” And they came near. And he said, “I am your brother, Joseph, whom you sold into Egypt. And now do not be distressed or angry with yourselves because you sold me here, for God sent me before you to preserve life. For the famine has been in the land these two years, and there are yet five years in which there will be neither plowing nor harvest. And God sent me before you to preserve for you a remnant on earth, and to keep alive for you many survivors. So it was not you who sent me here, but God. He has made me a father to Pharaoh, and lord of all his house and ruler over all the land of Egypt.
(Genesis 45:4-8 ESV)
One could easily imagine an unbeliever saying that this story teaches “Let us do evil that good may come” (Romans 3.8). The story prophesies the Gospel, as Paul explains it in Romans.
