Wants, Expectations, and Strife, Part 2

In the verse discussed in part 1 of this article (James 4:1-3), James talks about "wants." And what are expectation other than the things that I want from other and from life that have become a demand that I have placed upon them, at an emotional level at least? So when I do not get what I want, my flesh (which is a soft way of saying MYSELF) rises up in anger and frustration.

Instead of expecting and wanting everything to work out the way we think it should, we should accept things for what they are,  and make the best out of whatever comes. This attitude should apply to all of life, whether at work, relationships, traffic, or anything else, with Faith in God, trusting that He will protect us, lead us, and help us in all circumstances.

"Now there is great gain in godliness with contentment" 1 Timothy 6:6, ESV

This brings to mind a great prayer composed by Reinhold Niebuhr, The Serenity Prayer:

The Serenity Prayer
God grant me the serenity
to accept the things I cannot change;
courage to change the things I can;
and wisdom to know the difference.
Living one day at a time;
Enjoying one moment at a time;
Accepting hardships as the pathway to peace;
Taking, as He did, this sinful world
as it is, not as I would have it;
Trusting that He will make all things right
if I surrender to His Will;
That I may be reasonably happy in this life
and supremely happy with Him
Forever in the next.
Amen.
--Reinhold Niebuhr

How do you think the world would react to Christians that truly lived this way?
