Yahweh is a voice not a form. He is the sound of words only! Everything in creation has a voice, the voice of God speaks through every prophetic act. Salt has a voice and it speaks life to death in the water (2 Kings 2); oil speaks healing to sickness and disease (James 5); the shofar speaks salvation to the nation (Joshua 6); communion speaks life to every cell in your body (Luke 22); can you hear the voice of creation speaking the words of God as Psalm 19 says?
Then the crowning of God’s creation is people and He speaks to us and through us. Idols have mouths but cannot speak (Psalm 115); but you, but me we have a mouth and His breath in our lungs so His voice comes through our mouth and when we speak it’s the voice of God in the earth. Speak life, speak hope, speak God’s word for its His voice coming through you! Yahweh is a voice, He is the sound of words.
Deuteronomy 4:12 “Then the LORD spoke to you from the midst of the fire; you heard the sound of words, but you saw no form—only a voice.”
