What does Genesis 41:46 mean?
Joseph is now 30 years old. He was sold by his brothers into slavery at the age of 17 (Genesis 37:2, 28). Much of the last decade of his life has passed in an Egyptian jail, a "pit," with no earthly reason to believe he would ever be released (Genesis 40:14–15). At this point, Joseph has spent most of his adult life as either a prisoner, or a slave, or both. It would be natural to wonder if those years were wasted—especially as they dragged on without a clear purpose.And yet, God had a plan and a purpose for Joseph's life all along, even as the days, weeks, and months passed in obscurity and restlessness. God can reverse the circumstances of any person's life to accomplish His will for His people and the world. He has undeniably done so for Joseph, who will represent Israel's God even as he governs with authority given to him by Pharaoh. When all is said and done, Joseph will live most of his life—80 years after being given power (Genesis 50:26)—in a position of honor and prestige. With hindsight, he will come to understand the greater plan which God had in mind (Genesis 50:15–20).
Again, we're told that Joseph travelled throughout the land of Egypt, beginning to put into effect the plan he proposed to Pharaoh for saving the people from the coming famine (Genesis 41:28–36).
