Uncertainty? How is it a "good" thing?

My weekly inquiry partner cancelled, and I thought I wouldn't do The Work this morning.  Then, my dear friend calls and we move into doing The Work. Great! Turned out it was just what we both needed.  Just another example of how life is so kind. We did The Work on "I can't be at peace in uncertainty" both choosing our own situation of not knowing, and stressing out.  Same thought, similar reactions believing the thought, very similar experience of ourselves without the thought...freer, lighter, noticing it's ok to seem inactive, a relief not to know, being inspired and moved by people or other circumstances that show up.  Without the thought, little to no resistance, no blame.  We experienced mental and physical peace.  Well, the situations didn't change yet there we were feeling peace.  
Perfect segway into turnarounds.  "I can't be at peace with certainty"  I noticed even when I think I'm in the certainty of getting what I want, I may think of something that, if believed, creates doubt, stress, etc.  I seem to want the next thing. Hey, what happened to my certainty?  I liked it.  Wow, it changes quickly. Through it all, though, I'm playing God, in the business of thinking I can control and manipulate what happens and when. And, I was thinking certainty would bring peace? Thanks, no, I don't want the responsibility of knowing all, and missing out on the surprises and lessons.  
Aaaaah, next turnaround. "I can be at peace with uncertainty".  It seems every and any moment can change, does change. (Poof, there goes another one.) I've been at peace in many moments, even when things are completely uncertain, and when I'm listening to music, dancing, biking, etc.  I did get to sleep last night despite believing a thought that caused me some stress. That was peaceful.  I'm at peace when I'm very clear it is impossible to know.  I'm certain of uncertainty.  Can I just get that?  Certainly, uncertainty has brought me to this inherently uncertain moment.  So, I need to know?  That's just another thought, dear friends.  Is it true?  I have to know?  Want to know? Need to know?  Let's do The Work, and find out. Enjoy the moments of uncertainty.  They will certainly change.
