Hebrews 4:11-14 NASB
Therefore let us be diligent to enter that rest, so that no one will fall, through following the same example of disobedience. For the word of God is living and active and sharper than any two-edged sword, and piercing as far as the division of soul and spirit, of both joints and marrow, and able to judge the thoughts and intentions of the heart. And there is no creature hidden from His sight, but all things are open and laid bare to the eyes of Him with whom we have to do.
Therefore, since we have a great high priest who has passed through the heavens, Jesus the Son of God, let us hold fast our confession.
