For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and spirit, of joints and marrow, and discerning the thoughts and intentions of the heart. And before him no creature is hidden, but all are open and laid bare to the eyes of him with whom we have to do. Since then we have a great high priest who has passed through the heavens, Jesus, the Son of God, let us hold fast our confession. For we have not a high priest who is unable to sympathize with our weaknesses, but one who in every respect has been tempted as we are, yet without sin.
–Hebrews 4:12-15
