Chapter 6 completes a warning begun in the last verses of chapter 5. The author has deep points to make, but doubts that the readers are ready for them. Yet the only course of action is to press on: there is no time to re-establish the ABCs of the faith. Spiritual **immaturity prevents growth**, leading to doubt, discouragement, and eventually to judgment. Those who only scratch the surface of Christianity, then fall into disobedience, can't be restored to good standing until they've experienced some level of judgment. Rather than make that mistake, we should trust in the absolute promises of God, and the work of Christ, as we patiently pursue godly wisdom. Chapter 7 will resume the extensive discussion of Melchizedek's priesthood (BibleRef).
