S – For the word of God is living and effective and sharper than any double-edged sword, penetrating as far as the separation of soul and spirit, joints and marrow. It is able to judge the thoughts and intentions of the heart

Hebrews 4:12 CSB

O – Commentary:

For the Word of God is living (zōn) and active (energēs). Not only that, its penetrating power is greater than any double-edged sword and reaches the innermost being of a person so that it judges the thoughts and attitudes of the heart. In doing this, it is able to discriminate successfully between what is spiritual in man and what is merely “soulish” or natural (it penetrates even to dividing soul and spirit), and does so even when these often-contradictory inner elements are interwoven as closely as joints and marrow. The inner life of a Christian is often a strange mixture of motivations both genuinely spiritual and completely human. It takes a supernaturally discerning agent such as the Word of God to sort these out and to expose what is of the flesh.

“Hebrews,” in The Bible Knowledge Commentary: An Exposition of the Scriptures

A – The Word of God has the ability to distinguish between what is human and spirit.  This is mission-critical in our walk with God.  We are human and spirit.  Having a “resource” that helps us recognize and act accordingly in both realms is a huge advantage.  The fact that it is living and active allows it to work without changing since its inception.

R – Heavenly Father, thank you for the Word of God.  It is our “plumb line” in our walk with you.  It instructs, guides and brings comfort.  Help us to think, talk and act according to its instruction.  Allow it to permeate our lives so w can reflect your love to others.
