The following is adapted from a paper I wrote on The Rare Jewel of Christian Contentment. Jeremiah Burroughs presents the illustration of a quiet-hearted child in one of his chapters and this idea has dramatically affected the way I look at life:
Perhaps the greatest struggle in the Christian life is that of discontentment. We are called to be in the world, but not of it – so where do we fit? We long for heaven and eternal rest with God; at the very same moment we wish to feel settled and at rest in this life. Contentment in all things, like that which Paul speaks of in Philippians 4:11, seems elusive. The heart longs for rest but naturally rushes forward in life; it is not content to wait for what it truly wants. It is impatient, hurried, troubled, and restless. Burroughs compares our hearts to a child to help us better understand ourselves: Say there is a child who wants a piece of candy. Unfortunately, he has worked himself into a frenzy in his desire for it and he cannot be calmed down.
