Today we begin the book of Hebrews. There is no clear indication of who wrote the book, but possible authors have been Paul, Luke, Barnabas, Apollos, Silas, Philip, Priscilla and others. The purpose of the book is to present the sufficiency and authority of Christ. The book is a letter written to Hebrew Christians who may have been considering a return to Judaism, most likely because of a lack of understanding in Biblical truths leading up to Christ. One of the key verses in the entire book is Hebrews 1:3, The Son is the radiance of God’s glory and the exact representation of his being, sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the majesty in heaven.
