God's Word Will Reveal the Problem (Hebrews 4:12-13)

11Let us therefore strive to enter that rest, so that no one may fall by the same sort of disobedience. 12For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart. 13And no creature is hidden from his sight, but all are naked and exposed to the eyes of him to whom we must give account.


The subtlety of the temptation to self-dependence is highlighted by verses 12-13. The opening For strongly ties them to verse 11 since they explain what the Israelites who fell in the wilderness failed to heed. David asks, in Psalm 19:12, "Who can discern his errors?" The answer he gives in the psalm and that of the writer of Hebrews is the same. Only the Word of God, which is living and active and sharper than any double-edged sword, is capable of exposing the thoughts and attitudes of a single human heart! We do not know ourselves. We do not even know how to distinguish, by feelings or rationale, between that which comes from our souls (psyches) and from our spirits (pneumas). Even our bodily functions (symbolized here by joints and marrow) are beyond our full knowledge. Only the all-seeing eye of God knows us thoroughly and totally (Ps 139:1-18), and before him we will stand and ultimately give account.

The images the author employs in this marvelous passage are effective ones. Like a sharp sword which can lay open the human body with one slashing blow, so the sword of the Scripture can open our inner life and expose it to ourselves and others. Once the ugly thoughts and hidden rebellions are out in the open, we stand like criminals before a judge, ineffectually trying to explain what we have done. Yet such honest revelation is what we need to humble our stubborn pride and render us willing to look to God for forgiveness and his gracious supply.

Plainly, Scripture is the only reliable guide we have to function properly as a human in a broken world. Philosophy and psychology give partial insights, based on human experience, but they fall far short of what the Word of God can do. It is not intended to replace human knowledge or effort, but is designed to supplement and correct them. Surely the most hurtful thing pastors and leaders of churches can do to their people is to deprive them of firsthand knowledge of the Bible. The exposition of both Old and New Testaments from the pulpit, in classrooms and small group meetings is the first responsibility of church leaders. They are "stewards of the mysteries of God" and must be found faithful to the task of distribution. This uniqueness of Scripture is the reason that all true human discovery in any dimension must fit within the limits of divine disclosure. Human knowledge can never outstrip divine revelation.
