1, 2. Become Familiar With Levitical Law—We are to become familiar with the Levitical law in all its bearings; for it contains rules that must be obeyed; it contains the instruction that if studied will enable us to understand better the rule of faith and practice that we are to follow in our dealings with one another. No soul has any excuse for being in darkness. Those who receive Christ by faith will receive also power to become the sons of God (Letter 3, 1905).

3 (Malachi 1:13). Every Sacrifice Inspected by God—It is Christ who searches the hearts and tries the reins of the children of men. All things are naked and open before the eyes of Him with whom we have to do, neither is there any creature that is not manifest in His sight. In the days of ancient Israel the sacrifices brought to the high priest were cut open to the backbone to see if they were sound at heart. So the sacrifices we bring today are laid open before the piercing eye of our great High Priest. He opens and inspects every sacrifice brought by the human race, that He may prove whether it is worthy of being presented to the Father (Manuscript 42, 1901).
