Hebrews 4:10-12

10For whoever enters God’s rest also rests from his own work, just as God did from His. 11Let us, therefore, make every effort to enter that rest, so that no one will fall by following the same pattern of disobedience.

12For the word of God is living and active. Sharper than any double-edged sword, it pierces even to dividing soul and spirit, joints and marrow. It judges the thoughts and intentions of the heart.
