Since the beginning of time, what is the most perfect law ever given whereby men might live? Is it not the law God gave at Mount Sinai through His prophet Moses? The Ten Commandments form the bedrock basis for all of the Law of Moses, which only Israel received. God personally intoned the Decalogue from the top of the mountain, and the people trembled when they heard His voice (Exodus 20)! God has not given another law which so perfectly establishes His concerns for mankind and His own glory.
But did God not give us a new law in Christ Jesus? Indeed, the New Testament mentions, even in Galatians, the “law of Christ” (Galatians 6.2), but I contend that Christ’s law does not nullify or replace God’s Mount Sinai laws (Matt. 5.17-19).
But doesn’t Hebrews speak of nullifying the old law of Moses and bringing in a new law in Jesus? With our digital access to the biblical texts, it’s easy to search for “old law” and “new law.” I challenge you to run a search on those two phrases and read every instance you find.
What’s that? You couldn’t find a single instance of “old law” or “new law”? Interesting.
What you will find are references to “old covenant” and “new covenant” (Heb. 8.13; 9.2, 15; 12.24) and to a “first covenant” and “second covenant” (Heb. 9.1), but that’s not exactly the same as “old law” and “new law.” A covenant is an agreement between parties; law may be included within the covenant, but it’s not equal to the covenant itself. We would do well to distinguish between Old Testament moral laws (instructions towards holy living), ceremonial laws (such as sacrifice, temple worship, special days, and circumcision), and civil laws (such as specific penalties for breaking laws).
Jesus and His apostles continued to refer back to the Law of Moses for moral guidance. Jesus referred to Deuteronomy 6.5 and Leviticus 19.18 for the Greatest Commandment and it’s human corollary (Matt. 22.37-40). He told a young man in Matthew 19.16-19 to keep the commandments in order to have eternal life. Paul often taught Christians using the commandments and the Law (Rom. 7.7-12; 13.8-10; 1 Cor. 14.34; Gal. 5.14-15; etc.).
Moral law has been the same since God created man. When has it ever been right to murder, to lie, to cheat, or to steal? When God spoke the Ten Commandments, He was not giving the world something new; He was instructing Israel in His character and in how they ought to live before Him! God’s moral law, then, displays His holiness and provides a means for us to understand our right place before Him. But it also condemns, giving judgments for violations.
If the Law of Moses contains the most perfect revelation of moral law since time began, then the way to have a relationship with God must have been through the correct keeping of that law, right? Wrong! This is Paul’s contention in the letter to the Galatians. Notice:
I do not nullify the grace of God, for if justification were through the law, then Christ died for no purpose. (Gal. 2.21)
Now it is evident that no one is justified before God by the law, for “The righteous shall live by faith.” (Gal. 3.11; and notice Paul quotes from the Old Testament, Habakkuk 2.4, for this proof!)
Is the law then contrary to the promises of God? Certainly not! For if a law had been given that could give life, then righteousness would indeed be by the law. (Gal. 3.21)
Law has never given life, has never justified a man before God!
There is a huge reason that Paul never contrasts the “old law” with a “new law” in Christ. He always contrast the law with faith and grace. Just as the Jews were not and are not justified by law, neither are we justified by law. Any law.
Think on these things.
