Hebrews 4:12-13
12 For the word of God is living and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart.  13  Nothing in all creation is hidden from God's sight Everything is uncovered and laid bare before the eyes of him to whom we must give account. 

Hebrews 1:3
The Son is the radiance of God's glory and the exact representation of his being, sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven.
