Refractions

A straw in a glass of water seems to be broken at the surface line. Have you ever wondered why and how this happens. I mentioned earlier that I wasn't a scientist, but as an analyst and creative I look at this phenomenon and I question: I know the start of the line and how it continues, but what happens at this breaking point? Isn't this similar to a threshold or liminal space, where we can see what came before and we can see what comes next, but we don't know quite how to get there?
I could get obsessed with this particular point and get bogged down in what I know or start a new story of what happens at this particular point. Just imagine... As a creative and person of faith I tend to focus on the positive possibilities and my mind starts to twirl with ideas. This refraction point is where I stand on the beach and look toward the sea and start dreaming of travelling to exotic places, or like one of my favourite Irish saints, Brendan, would step into a little rudderless boat and let the wind of God determine where I would end up. The refraction point becomes a point where faith and trust is required, because we honestly don't know what's next. 
For me this point of refraction was when I said yes to more chemo. I knew a little bit what to expect, but didn't know how it would affect me until I went through it. 
Every time I start a new quilt or other creative project, there's this point of refraction: I know what I have to work with and somewhat of an idea what it will look like. But really no idea of what the end result will be. 
Every time we go through a season of loss or change we come to this point of choice: do I sit back in fear or do I step out in faith and trust that the end will be OK?
