Our text from the Letter to the Hebrews today begins with a vivid image:
The word of God is alive and active, sharper than any double-edged sword. It cuts all the way through, to where soul and spirit meet, to where joints and marrow come together.
A sharp sword was the deadliest weapon of ancient times- the Kalashnikov of the Roman era. So this image is like something from a very bloody battle- or a very graphic horror film. A sword that cuts through flesh, joints and marrow is an unsettling thought. And it is used to describe the word of God.
