Faith without works, like it or not, isn't faith to begin with. And what we do, practically speaking, might be accompanied by occasional explanation when it's requested. But the work, if you like, is faith enough. Witness enough too. The only witness, actually. Witness isn't a personal profession of faith. Actions speak, and profession, at best, merely elaborates on actions, explaining the why and the how. We need not add how strongly we believe in God.
We're doing what we believe, and we're not doing what we don't.
-- David Dark, The Sacredness of Questioning Everything
