We are all striving for the elusive "abundant life" or longing to flourish. The culture defines this as success in terms of power, position, and wealth. It should be no surprise that this is not how Christ describes success.
We all think economically, Christians included, whether or not we know it. We all make choices about how to obtain and spend scarce resources. Most of us also care deeply about how to deal with scarcity, distribute wealth, and maximize prosperity throughout our society. The only difference is how clearly we think through these choices and valuations.
Charles Spurgeon says, "I think that is a better thing than thanksgiving: thanks-living. How is this to be done? By a general cheerfulness of manner, by an obedience to the command of Him by whose mercy we live, by a perpetual, constant delighting of ourselves in the Lord, and by a submission of our desires to His will."
