All these children are full of nervous energy that accomplishes nothing except exhaustion. Some parts of life, even those that lead to health, are painful. But the only way around these difficult parts is through them. Advent waiting can be like labor pains. New birth will be the result, but the process can be long and painful.
Births happen when they happen.
Our role, however active, is to wait for the baby to arrive. Even the everyday act of growing up is fraught with challenging times in which waiting is at the heart of the matter. It is not time for certain things, until it is time. If you have ever been a teenager you know how maddeningly real this waiting stuff is. All of adolescence is an advent time.
