How is the book of Exodus a picture of redemption?
The book of Exodus pictures redemption by Israel being redeemed out of Egypt, and it perfectly pictures you and I being redeemed out of the shackles of sin and brought to a life of freedom. The commanded three days' journey out of Egypt is indicative of the resurrection.
Les explains that the whole book of Exodus is a picture of redemption: first, Israel being redeemed out of Egypt, but also the perfect picture of you and I being redeemed out of the shackles of sin and brought to a life of freedom. He points out that God told Moses and Aaron He wanted Israel to go three days' journey out of Egypt, and that only one thing can separate a person from slavery. The three days, he says, are indicative of the resurrection. This fits his broader observation that everything in creation rests upon a trinity of sorts—time, space, and matter, or water as liquid, solid, and gas—though he avoids using 'trinity' for water because we normally think of the Godhead.
