Genesis ends with these words from Joseph "you meant evil against me, but God meant it for good" (Genesis 50:20). The book of Genesis showed us a God who was faithful and true to His promises. The God of creation, the God of Abraham, the God who worked to save His creation from the impact of sin.
In Exodus, the same God is working to save a people from slavery and exile. Exodus is a book about the return of a people into the promises of God and a renewed relationship with God. As we follow Moses and the nation in the desert, we will often be reminded that Moses points to Jesus: the One who came to seek and save the lost from every nation.
