"Noblesse Oblige is a French phrase that means, literally, "nobility obligates." The idea is that if one was born into the privileged life of the nobility, the French aristocracy, that one had an obligation to use that position for the good of every man. The problem was that the French nobility wallowed in the privilege and forgot the obligation. That didn't end well - remember the French Revolution?
In a very real sense, we believers are the Nobility of Heaven. We didn't earn the position, we were born (again) into it. We are children of the King of Heaven. This privileged status is ours purely by grace. Well, then, is the Christian life all wellness and prosperity followed by frolicking through the daisies of Heaven forever? Or do we have obligations?
1 Peter 2:9 shows us our privilege:
"But you are a chosen people, a royal priesthood, a holy nation, a people for God’s own possession..."
and it also shows us our obligations:
"...so that
you may proclaim the excellencies of Him who has called you out of darkness into His marvelous light."
There it is. There's your obligation if you've been born into the royal family. You've got to proclaim His excellencies. When we do this, others will be eager to be born (again) into royalty as well.
I think some of the major ways we proclaim His excellencies are to
*Reflect God's Image.
*Steward the domain that He's given.
*Fight in the arena He's designed you for.
*Claim a mountain for your people.
So don't be a Marie Antoinette. Appreciate the privileges. Fulfill the obligations.
