Having God’s Word inscribed on your heart, the Word comes alive within your soul and spirit to the point where you can’t sit still or shut up.  It reminds me of Jeremiah 20:9. “But when I tell myself, I’ll never mention Your name or speak for You again, it’s no use. The Word of God burns in my heart; it is like fire in my bones, I try to hold it all in, but I cannot.”
