An unknown author writes this letter to Jewish Christians to explain the significance of Jesus Christ. God has revealed Himself through prophecy and various ways, but in the New Testament He has been revealed through Jesus, who is the incarnation of God in human form who went to take on the penalty of humanity's sin. The superiority of Jesus gives the basis for living according to the New Testament principles as opposed to the Old Covenant prior to the cross. Continuing to live by the Old Testament is a failure to recognize the importance of Jesus' sacrifice.
