John Ritenbaugh, focusing on the description of the New Covenant in Hebrews 8:10, reminds us that, although God never intended the Old Covenant to endure eternally, the spiritual and immutable law (shared by both the old and new covenants) was to last forever. God did not nail His holy Law to the cross, as major Protestant denominations mistakenly declare. Rather, God nailed the penalty for our past sins, paid for by the blood of Jesus Christ, to the cross. The wages of sin is death. When Jesus Christ fulfilled the Law, He not only provided a model as to how His called-out ones are to keep it, He magnified it and raised the standards of compliance, targeting not only behavior, but motive—the whole spiritual process which underlies any sin. To give His called-out ones the ability to reach these higher standards, He gifted them with the Holy Spirit, thereby empowering them to displace carnality with Godly character. God does not create such character by fiat. Rather, it grows steadily with our determination to participate and cooperate with God. The purpose of all of God's covenants with mankind is to create character and stop sin. The New Covenant, as explicated by Hebrews, contains "post graduate" responsibilities far beyond the letter-of-the-law instructions given in Leviticus. Unlike the faulty Protestant assumption that Christ has done all the work of salvation, Christ warns His people that they must soberly count the cost because of the vastly higher standards established in the New Covenant. Christ promises, through the means of His Holy Spirit, the power to do His will, thereby giving His people the necessary tools to achieve membership in the family of God.
Some think Galatians 3:19 means that God's law has been done away. Earl Henn explains how certain misunderstandings have led people astray on this verse.
John Ritenbaugh provides a summary of the Covenants, Grace and Law series: 1. Realize the position carnal man comes from: completely under Satan' sway, antagonistic to God's law (Romans 8:7). 2. Always work from clear, unambiguous scriptures (Matthew 5:17-19). 3. Be strengthened by the examples of Christ and His apostles keeping specific laws, including the Sabbath and holy days (I Peter 2:21). 4. Paul explains the means of justification (not salvation but the first step in a process; God imputes righteousness where it does not logically belong). 5. God's overall purpose is to create us in His image, including His righteous character. He is reproducing Himself (Genesis 1:26)! 6. God's purpose for the Old Covenant is as a bridge leading to Christ (Galatians 3:17-24). 7. The way Paul and others use terms important to this doctrine (bondage, circumcision, yoke, law, etc.) should be seen in their correct context.
