We know and remember through the body, not just our brains.
Chapters 12-26 invite us to know how we should live in the light of God’s revealed character and past faithfulness. One of the primary ways we know and learn things is through our bodies. The instructions of 12-26 are meant to be lived, to become habits—ways of life. This would give the people of Israel a lens for understanding the world they were not even aware they were wearing.
We are no longer under the burden of the law; In other words, Jesus has freed us from the necessity of the ceremonies and sacrifices as a way to keep the covenant. We are now free, but we are free to live under the grace of Christ and to live for him instead of sin.
We must continually remember what we have been saved from and what we have been saved into. Remembering what we were saved from reminds us of God’s incredible grace and motivates us to be just and graceful people. As we remember we more and more come to the knowledge of God and our place in his Kingdom. As dearly loved children, rescued by his grace and called to life with him. A life to the full—full of the joy of his presence where we enjoy him forevermore.
