A. For the word of God: God’s Word diagnoses the condition of man with a surgeon’s precision. It lays open the heart and accurately discerns spiritual health. In the case of those the writer to the Hebrews first addressed, they were too ready to follow in the failure of the children of Israel and to give up strong, living faith.
B. Living and powerful: When the word of God exposes our weakness and unbelief like this, it demonstrates its inherent power, sharpness, and accuracy. It bears constant reminding that as we submit ourselves to the word of God, we do it for far, far more than intellectual knowledge or to learn Bible facts. We do it for the ministry of the Word, because God meets us in His Word and the Holy Spirit works powerfully through the word of God. This spiritual work of God’s Word goes far beyond the basic educational value of learning the Bible.
