It’s been many years since I struggled with the issue of the New Testament canon.
I was never in any doubt that the NT was God speaking, or that we had an accurate record of Christ’s life and its implications in our hands today (or, for that matter, that the NT provides unshakable authority for the entire OT canon). My difficulty, seeking to serve the Lord by teaching the Word in my mid-twenties, was finding the best way to explain my confidence in scripture to younger believers.
Somehow, shrugging and invoking divine providence just didn’t feel adequate.
