A Christian comes to contentment, not so much by way of addition, as by way of subtraction. That is his way of contentment, and it is a way that the world has no skill in. I open it thus: not so much by adding to what he would have, or to what he has, not by adding more to his condition; but rather by subtracting from his desires, so as to make his desires and his circumstances even and equal… [A] heart that has no grace, and is not instructed in this mystery of contentment, knows of no way to get contentment, but to have his possessions raised up to his desires; but the Christian has another way to contentment, that is, he can bring his desires down to his possessions, and so he attains his contentment.
