You are the salt of the earth; but if the salt has become tasteless, how can it be made salty again? It is no longer good for anything, except to be thrown out and trampled underfoot by people.
For the word of God is living and active, and sharper than any two-edged sword, even penetrating as far as the division of soul and spirit, of both joints and marrow, and able to judge the thoughts and intentions of the heart.
