Well Said: God speaking

The theme of God speaking will run like a thread through Hebrews. When introducing biblical quotations, instead of saying "it is written," Hebrews will invariably use phrases like "God says" or "he has promised." Scripture is not confined to the dusty pages of ancient manuscripts; it is a living and active word through which God continues to speak, addressing his people personally her and now (see 3:7, 4:12).
