Why is it difficult to be content when you have so much?

On the surface, it seems unnecessary to instruct someone to be content in times of prosperity. However, times of prosperity and abundance provide some of the strongest temptations to pull our hearts away from God. Jeremiah Burroughs was keenly aware that the riches of this world compete for our affections and challenge our contentment in Christ. Originally prepared as an appendix to The Rare Jewel of Christian Contentment, this book provides an important conclusion to Burroughs's sermon series on Philippians 4:11-12: 'I have learned in whatsoever state I am, therewith to be content. I know both how to be abased, and I know how to abound: every where and in all things I am instructed both to be full and to be hungry, both to abound and to suffer need.'
