This has always been a difficult passage for me. No doubt this has been discussed before. If, as most of us do, believe in the harmony of the Bible, and believe in eternal security, it would be interesting to know what others think about the phrase "if they fall away." Is the author speaking to those already saved and this is a hypothetical situation, or is this people who are at the brink of salvation and never acquire that saving faith? If so, are they lost forever because they went to the brink? Is there a better explanation? Thanks for your thoughts.
