"For the word of God is 

living, 

and active,

and sharper,

than any two edged sword,

and piercing

as far as the division of soul and spirit,

of both joint and marrow,

and able to judge the thoughts and intentions of the heart."

Hebrews 4:12

"Sanctify them in the truth;
Your word is truth."  John 17:17

There is only change into Christlikeness when the Word of God is slicing away self and being replaced with Jesus...
