After reading your ping, I sat for a moment reflecting upon the Word which you included in your post. Something struck me, and in double checking, I am posting the preceding two verses in Hebrews 4:
12 "For the word of God is living and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart. 13 Nothing in all creation is hidden from God's sight. Everything is uncovered and laid bare before the eyes of him to whom we must give account."
Hebrews 4:12!! Amazing!!! Thank you so very much for sharing this wonderful verse from His Word!!
