Not to be snarky, but even with a Bible in our native tongue, we're still in peril. Merely having a perfect book, which is a miracle in itself, is no promise of success. We have the remarkable ability to avoid putting into practice what we know to be true. I know you're not arguing that people can do as they wish as long as they acknowledge the whole of Holy Scripture, but just because we're not Judaisers or Muslims doesn't mean we're in the clear. I'd much rather have one of those "Red Letter Christians" follow what Jesus said than a person who taught the whole Bible but lived none of it.
