It says in scripture (Isaiah 55) that even the trees of the field will clap their hands in response to His word. Elsewhere it says the rocks will cry out if none else cry out. I agree with Augustine, that I cannot be silent, that silence as a non-action even if I am dumb, in response to all that God has done and is doing, and all He is, is simply not an option: "Yet, O my God, my life, my holy Joy, what is this that I have said? What can any man say when he speaks of thee? But woe to them that keep silence -- since even those who say most are dumb." - Augustine
