Hebrews 4:12-13

12For the word of God is living and active and full of power [making it operative, energizing, and effective]. It is sharper than any two-edged sword, penetrating as far as the division of the 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.

13And not a creature exists that is concealed from His sight, but all things are open and exposed, and revealed to the eyes of Him with whom we have to give account.
