Hebrews 4:11-12

BLB(i) 11 Therefore we should be diligent to enter into that rest, so that no one should fall by the same example of disobedience. 12 For the word of God is living and active, and sharper than any two-edged sword, penetrating even as far as the division of soul and spirit, and of joints and marrows, and able to judge the thoughts and intentions of the heart.
