The writer of Hebrews points out that God’s Word diagnoses the condition of man with a surgeon’s precision. It lays open the heart and accurately discerns spiritual health, as scholar David Guzik puts it.
"For the word of God isliving and powerful, and sharper than any two-edged sword, piercing even to the division of soul and spirit, and of joints and marrow, and is a discerner of the thoughts and intents of the heart." - Hebrews 4:12
