"Let your life speak," or more precisely, "listening to your life" is a thought that came from Frederick Buechner. And indeed it is a wise thought.
I often read (on blogs) or hear someone else, and rather wish I was like them in some way. But what's important for us is to let our own lives in and from God speak to us and to others. We need to listen to our lives, and more precisely to God through our lives.
This means that I don't worry about all my limitations, but I go with what I have, and look to God to do the work that only he can do.
It's a strength and a blessing to learn more and more to accept ourselves fully, where God has us, and to accept others fully where God has them. And to do so with joy, realizing all good is a gift from God. And that he indeed is speaking to us through our lives. And through the lives of others.
