Is the word of God things themselves?

I once heard that the word of God is things themselves. But I can't find the source. If someone knows and can tell me, I would be very grateful! We know that in the Gospel of John, the Word of God is logos and the Word became flesh. We have also heard that many people in history say that they saw God in a vision and that God spoke directly to them, where the "word" was a voice. So, are there any arguments for and against the idea in the title, such as in the texts of the Bible, the Fathers, theologians and philosophers?
