Hebrews is addressed to a people living at the end of an era, who were drifting away, had lost their devotion, and were no longer motivated by zeal.
The book of Hebrews provides reasons to recapture flagging zeal, focusing on the reason for our hope and faith, establishing Christ's credentials.
Like the Ephesians, the weary veterans in Hebrews were becoming apathetic through outside pressures, losing their former zeal and devotion to Christ.
In terms of spiritual insight, Hebrews is a pivotal book, whose function is to bridge the purposes and themes of the Old and New Testaments.
In Hebrews, we learn that Jesus is the only- begotten Son, creator and heir of all things, the express image of God's person, and has purged our sins.
Love for this world will inevitably bring disillusionment. Because the world is passing away, our priorities should be to fear God and keep his commandments.
