Do not fear those
who kill the body
"Do not fear those who kill the body but are unable to kill the soul; but rather fear Him who is able to destroy both soul and body in hell."
The value here is placed on the eternal soul of the individual. The body is just the vehicle, the wrapper, the temporary home of the person. It will wear out and die.
We are to hold reverence and fear the One who will judge and the One with power to save or to condemn with eternal consequences.
Proverbs 1 says Fear of the Lord is the beginning of knowledge and wisdom.
