As Fragile as a Chihuahua

Just recently my chihuahua was attacked by a large dog. She
broke a rib and punctured a lung. It was a rather traumatic experience for her. However, she was really great through the whole thing and bounced back within days and now is as good as new. The attack happened on a run that we went on nearly every day. I had stopped bringing her on this run due to her health and to avoid another attack. The other day I decided to bring her. She was ecstatic to say the least. She ran and sniffed and wagged and jumped and got into everything as she normally would. I on the other hand had a hard time trusting. It got me thinking about life in general and how we must choose to live everyday. Day in and day out, we may think we are safe but the truth is we are as fragile as my chihuahua. It is only our minds that keep us safe. The truth is at any second everything can change. We can receive news that absolutely changes everything, someone we are close with can decide to change their lives and in turn change ours, an accident can occur or a miracle can occur. The only thing that truly keep us afloat in the river of life is our faith.... besides that we simply glide along with the current. Without trust and faith we can never relax we are left to our own devices and must swim with all our strength to get where we are going. 

So this left me with the question. How will we live our lives? Do we let ourselves play with abandon despite the consequences that may meet us around the next corner? Should we play it safe so that we may change our fate and avoid complications? Or can we trust ourselves, jump on our raft of faith and enjoy the ride?
