Bible: Hebrews 4:11-12

4:11 Thus we must make every effort to enter that rest, so that no one may fall by following the same pattern of disobedience. 4:12 For the word of God is living and active and sharper than any double-edged sword, piercing even to the point of dividing soul from spirit, and joints from marrow; it is able to judge the desires and thoughts of the heart.
