In his book The Ten Commandments Arthur W. Pink looks into the origin of the The Commandments, their purpose for the Jewish people and their significance for Christians."There are two things which are indispensable to the Christian's life: first, a clear knowledge of duty, and second, a conscientious practice of duty corresponding to his knowledge. As we can have no well-grounded hope of eternal salvation without obedience, so we can have no sure rule of obedience without knowledge. Although there may be knowledge without practice, yet there cannot possibly be practice of God's will without knowledge. And therefore that we might be informed what we ought to do and what to avoid, it has pleased the Ruler and Judge of all the earth to prescribe for us laws for the regulating of our actions."Arthur Walkington Pink was an English Christian evangelist and Biblical scholar known for his staunchly Calvinist and Puritan-like teachings. Though born to Christian parents, prior to conversion he migrated into a Theosophical society (an occult gnostic group popular in England during that time), and quickly rose in prominence within their ranks. His conversion came from his father's patient admonitions from Scripture. It was the verse, Proverbs 14:12, 'there is a way which seemeth right unto a man, but the end thereof are the ways of death,' which particularly struck his heart and compelled him to renounce Theosophy and follow Jesus.
