It might seem like we have a big role to play in this life. It is probably something we have all wanted at some point, to play a major role is this great drama, to be the one to make a difference and admired by many.
I have a suspicion though that there are no big roles to play. That all the roles are small roles. This means that we are not dependant upon a few doing their bit. We are dependant upon us all doing our bit.
This exalts rather than diminishes the importance of each person playing the small role they have been given. Without each person playing their small role, the emergent properties of all these roles put together would be different and not as whole.
The more we are comfortable with the role we are called to play, and to play it with wholeheartedness, the better life will be for all of us.
