The Book of Hebrews is filled with exhortations and warnings about the subtlety of apostasy. The mission of the book is also to strip false assurance from those who had not yet made a commitment of faith. Exhort one another daily, while it is called Today, lest any of you be hardened through the deceitfulness of sin. His exhortation throughout is directed to professing believers who have not yet been born again because they stop short of saving faith in Jesus Christ.
This program is already assigned to that list.
