Things get difficult if you hold that the Bible is only a human product; but they also get difficult when the Bible is treated only as a set of timeless instructions from God, irrespective of the actual process by which the texts arose. The Bible needs to be read, prayerfully and discerningly, in the company of as many other believers as possible, so that we can learn some wisdom from each other as to what exactly God does want to tell us. Hearing the truth in Scripture means expecting the Holy Spirit to be at work both in the text and in the community that reads it.
