Henry Law once wrote this about the book of Leviticus, “The main lesson of this Book is Christ. He is the light and luster of each part. To read aright, is to walk up and down with Him. Have we thus found? Is He more deeply engrafted in our hearts? Is He more closely enshrined within our thoughts? Has He become the mainspring of our being? Have we no longer any mind but His? Christ is the juice—the life—the heart-blood of Leviticus. If it instruct not thus, the veil is on the reader’s mind. He gropes in darkness amid glorious rays.”
We must not think that the Levitical laws were sort of a failed venture on God’s part. It’s not as if He came up with a temporary fix that didn’t quite end up working out. Rather, God, being sovereign over history orchestrated these sacrifices, festivals, and ordinances in order to reveal our need for Christ. A vital doctrine is distilled from Moses’ Law: the three uses of the Law. First, the Law is a restraint on evil; in this way the Law functions as God’s border patrol for mankind. Secondly, the bright holiness of the Law functions to reflect back to mankind his deadness & depravity; it is like a mirror which shows us the truth about ourselves. Third, it reveals Christ, the only righteous man who not only died in our place, but also imputes His righteousness to us, by faith. The whole point of Leviticus is to get Israel to see that their only hope was if God delivered them through the Messiah. That is our only hope as well.
