Hebrews 4:12

For the word of God is living and active. Sharper than any double-edged sword, it penetrates even to dividing sould and spirit, joints and marrow; it judges the thoughts and attitudes of the heart.

I guess I have something to say now, when somebody asks me what is my favorite verse. It's so fascinating that, even though our hearts get hardened now and again, there's truth in that God is able to see past that.
