Hebrews 4:12-13

4:12 For the word of God is living and active and sharper than any double-edged sword, piercing even to the point of dividing soul from spirit, and joints from marrow; it is able to judge the desires and thoughts of the heart. 4:13 And no creature is hidden from God, but everything is naked and exposed to the eyes of him to whom we must render an account.
