Colin Hansen has posted an excellent article on the difficult warnings of Hebrews regarding our salvation and eternal security.
The Book of Hebrews daunts even the most gifted preachers and scholars. For one thing, we don’t know the author. He quotes the Old Testament at length and repeatedly, but his method of interpreting these passages doesn’t always make sense to readers. His arguments about angels, Moses, and the temple require more than cursory understanding of the Hebrew Bible.
And then there are the s0-called warning passages. It might be hard at first to grasp the significance of the priest Melchizedek, but many Christians viscerally understand the practical importance of these warnings. Can I lose my faith? What if I doubt? Fail to overcome sin?
To answer these questions and more, I turned to the acclaimed scholar Peter O’Brien, professor emeritus at Moore College in Sydney, Australia. Many who have studied Ephesians, Colossians, Philemon, and Philippians have benefited from his rich, insightful, and faithful commentaries. He has also written an immensely helpful commentary on the Letter to the Hebrews. He draws on some of that study to help us understand the famous warning passages in their immediate and canonical context.
