The Ten Commandments
Can the ten commandments bring liberty? Are they still relevant in the modern world? A generally accepted principle among many professing Christian churches is that all aspects of the old covenant served to point the nation of Israel to the coming sacrifice of Jesus Christ; once that sacrifice was made, the entire package of old covenant laws became obsolete. According to this concept, adherence to a written code of laws, like the commandments, is no longer relevant to Christians.
Christ, through the prophet Jeremiah, foretold that He would write His law on our hearts under the new covenant (Jeremiah 31:33; Hebrews 8:10), but does this mean that we will automatically obey God's law (e.g. the ten commandments) simply by accepting in faith that Jesus is our personal savior?
Let us notice what one of the inspired writers of the New Testament had to say about all the commandments, not just the ten of Exodus 20. The apostle James states that unless we are doers of God's word and not just hearers (James 1:22) we are deceiving ourselves (James 1:22). In verse 25, he tells us how to be doers of the word, which is by looking into the perfect law of liberty and continuing in it. In other words, we are to LOOK into God's inspired word, the Bible, to find the "perfect law of liberty" and then KEEP that law!
Does this contradict Christ's statement that He will write His law on our hearts? No! However, it does provide insight into the way in which Christ writes it. It shows that, upon our acceptance of His sacrifice, Christ does not simply turn us into spiritual robots who automatically have knowledge of what His law is and how to keep it. Rather, after conversion, He expects us to study the Bible so that we can understand the perfect law of liberty and then abide by it.
However, what is the perfect law of liberty to which James referred? In Matthew 22:36-39, Christ reveals what are the two greatest commandments. The first one is we are to love God with all our heart, soul and mind; and second, we are to love our neighbors as ourselves. Although this tells us that the overall principle of the law is outgoing love toward God and fellow man, it does not give us the details of how we are to show that love.
In 1John 5:3, the details of how to love are defined in relation to obeying the ten commandments. However, which ones is he referencing? Undoubtedly, to the laws of GOD which, when transgressed, result in sin (1John 3:4). The apostle Paul tells us which ones these are. He writes that he would not have known what sin was except the law told him not to covet (Romans 7:7). This directly references one of the laws found in Exodus 20, the same ones James was referring to when he wrote about the perfect law of liberty.
