This month, in the Shambhala Sun magazine, Norman Fischer writes about this very notion:
Years ago I went to the Wailing Wall in Jerusalem and did what all tourists there do: wrote some words on a scrap of paper that I tucked into a crevice in the wall. When I closed my eyes and touched my head to the warm stone, it came to me: “All language is prayer.” This must be so. Who is it we are speaking to when we speak to anyone? To that person, and also past him or her to Out There. If there is language, it means there is the possibility of being heard, being met, being loved. And reaching out to be heard, met, or loved is a holy act. Language is holy.
