The apostle Paul told us that The Law (10 commandments) is "spiritual". Jesus said that to hate is the same as murder. The Scriptures teach us that, Christians, as the bride of Christ -commit adultery when we become "one" with the world. To take God's name in vain means to call ourselves "Christians" when we are not. These truths and so many more are explained in detail in this great study of the book of Hebrews from 2004 by Dr Mack Griffin at Emmanuel Theological Seminary.
