John Calvin on contentment

"the happiness promised us in Christ does not consist in outward advantages--such as leading a joyous and peaceful life, having rich possessions, being safe from all harm, and abounding with delights such as the flesh commonly longs after. No, our happiness belongs to the heavenly life!" John Calvin http://www.reformedtheology.ca/quotes_topic.htm
