From Contentment: A Godly Woman's Adornment

We will never know contentment in Christ if we seek him as
a divine referee, however unfairly we may have been treated.
His work in our lives is not about making sure we get the
maximum benefits in the here and now, even when we are
entitled to those benefits. In fact, real contentment often
comes when we willingly embrace the loss of them.

The second thing Jesus does is reveal the spirit of
covetousness that underlies most of our prayers about
obtaining our share. […] We will never find contentment—
freedom from that angry feeling of unfairness—by getting
the things that are rightfully ours. We will find it by
letting go of our entitlement to them.
