I will take you to be my people, and I will be your God, and you shall know that I am the Lord your God, who has brought you out from under the burdens of the Egyptians. I will bring you into the land that I swore to give to Abraham, to Isaac, and to Jacob. I will give it to you for a possession. I am the Lord (Exodus 6:7-8). Not only does God save Israel out of Egypt but wants to bring them into the Promised Land. Moses is sent by God to save Egypt out of slavery; later down in history God sends Jesus to save mankind from slavery to sin.
In this podcast Peter explains how the works of Moses and Joshua correlate to the works of Jesus pertaining to our salvation.
