Faith is taking the first step even when you don't see the whole staircase.
Martin Luther King, Jr.
That quote is especially powerful for me. I'm not thinking as much about religious faith, exactly, at least not any partiular theology, but about the choice to put one foot in front of the other and take the next little risk, to keep loving and lifing actively, knowing that the bottom can fall out in any way at any moment. I have no idea what the whole staircase looks like, and know I can't know. Taking each step is enough.
