Tomorrow as I preach I'll be asking and answering the question, "What is the gospel?" In part I'll be relying on a definition offered by J.I. Packer in his introductory essay to the John Owen work, The Death of Death in the Death of Christ. There Packer describes the biblical gospel as "always and essentially a proclamation of Divine sovereignty in mercy and judgment, a summons to bow down and worship the mighty Lord on whom man depends for all good, both in nature and in grace."
Packer's essay on the gospel is a tremendous treasure, well worth the read. It is perhaps the best short essay on the gospel that I have ever read, and I commend it to you for your reading.
