The book of Hebrews is
unique; its style is distinct from that of other letters in the New
Testament. Though we don't know who wrote Hebrews or exactly to whom it
was written, it's clear that the book was written to believers in Jesus
who had become exhausted. They were tired of being Christians, tired of
suffering for their faith, and tired of waiting for Jesus to come back.
In their burned-out state they were in danger of drifting in their
journey with God. So the writer of Hebrews aims to encourage these
believers to hold on, in God's strength, by refocusing on the author and
founder of their faith the Lord Jesus Christ.
