2 Behold, I am God; give heed to my word, which is quick and powerful, sharper than a two-edged sword, to the dividing asunder of both joints and marrow; therefore, give heed unto my word.
This metaphor is quite graphic but also profound. It reminds me of another favorite in the Book of Mormon:
“5 And now, as the preaching of the word had a great tendency to lead the people to do that which was just–yea, it had had more powerful effect upon the minds of the people than the sword, or anything else, which had happened unto them–therefore Alma thought it was expedient that they should try the virtue of the word of God.”
The word of god pierces deep into our joints and into our very essence. It resonated deeply with something eternal within us. Therefore, when we hear divine truth we cannot ignore it. It tugs upon us and draws us towards it. We can of course reject it. We can return to ignorance. We can continue to hold on to the doctrines of man. But we are forever impacted by having come into contact with divine and eternal truth.
