Hebrews 4:12–13
4:12 For the word of God is living and active, and sharper than any two-edged sword, piercing even to the dividing of soul and spirit, of both joints and marrow, and is able to discern the thoughts and intentions of the heart.
4:13 There is no creature that is hidden from his sight, but all things are naked and laid open before the eyes of him to whom we must give an account.
