Hebrews 4: 12
For the word of God is living and active and full of power [making it operative, energising, and effective]. It is sharper than any two-edged [a]sword, penetrating as far as the division of the [b]soul and spirit [the completeness of a person], and of both joints and marrow [the deepest parts of our nature], exposing and judging the very thoughts and intentions of the heart.
