 The Word of God is living and active, sharper than any two-edged sword, Hebrews 4 tells us. And able to judge the thoughts, I'm jumping ahead in the verse, able to judge the thoughts and intentions of the heart. Why is it sometimes when you read the Scriptures and you go, oh, how could God know that about me? That's speaking to what I'm wrestling with. How could God know that? Because He knows our hearts. His Word speaks.
