As you continue to listen to these instructions on sacrifices, I encourage you to imagine what it would be like to experience these sacrifices. The warmth of a live animal and the feel of coarse hair under your hand as the animal is slaughtered for your sin; the smell of incense and roasting meat; the sight of blood splattered onto the clean, hand-crafted tunics of the priest who go before the Lord to make atonement. It all communicates something deeper about the gravity of sin and the graciousness of God toward those who seek forgiveness. Towards the end of our reading we’ll see what happens when Aaron’s sons decide to worship the Lord as they see fit, rather than by God’s instructions. God takes obedience in worship seriously.
