1 How sure the Scriptures are! God's vital, urgent word, as true as steel, and far more sharp than any sword: So deep and fine, at his control they pierce where soul and spirit join. 2 They test each human thought, refining like a fire; they measure what we ought to do and to desire: For God knows all exposed it lies before his eyes to whom we call. 3 Let those who hear his voice confronting them today, reject the tempting choice of doubting or delay: For God speaks still his word is clear, so let us hear and do his will!
