We left off the story at the end of Genesis with Joseph’s coffin in Egypt and his words about God visiting his people in the future to bring them up from Egypt.  In Exodus, we pick up the story some generations later when the Hebrews found themselves enslaved and calling out to God for rescue.  He heard them and did indeed rescue them through the agency of a man named Moses.  However, things did not go smoothly in the aftermath, which points to the fact that this visitation was not the ultimate one.  Exodus points us forward to a greater visitation and a greater rescue.
