Hebrews 4:12-15

12 For the word of God is living, and active, and sharper than any two-edged sword, and 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.

13 There is no creature that is hidden from his sight, but all things are naked and laid open before the eyes of him with whom we have to do.  14 Having then a great high priest, who has passed through the heavens, Jesus, the Son of God, let us hold tightly to our confession.  15 For we don't have a high priest who can't be touched with the feeling of our infirmities, but one who has been in all points tempted like we are, yet without sin.
