"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
"Whenever those things present themselves to us which would lead us away from resting in God alone, let us make use of this sentiment as an antidote against them, that we have sufficient cause for being contented, since he who has in himself an absolute fullness of all good has given himself to be enjoyed by us.
In this way we will experience our condition to be always pleasant; for he who has God as his portion is destitute of nothing which is requisite to constitute a happy life."
— John Calvin
