Peace: When the Greatest Evil, becomes the Greatest Gift

Peace. It's funny and tricky word in relation to living the Christian life.
Similar to mercy, forgiveness, or love, its a word mentally I understand what it means, but on a heart level I am very much still a beginner.
The angel choir sang it to the shepherds that cold night in Bethlehem, "Glory to God in the Highest. Peace on earth to men of good will." Peace on earth. Such a simple, pretty phrase we read in the Christmas story, but so easily and quickly forgotten. I have struggled and wrestled with this idea of peace a lot in my life; of finding peace in the midst of pain, suffering, sadness, and even in anger. 

Peace is believing God's provision is everywhere, because Jesus is everywhere. Because His presence can be found everywhere and in anything, no matter what it is. 
This Advent, I am using a devotional written by Ann Voskamp. Part of what she wrote yesterday, reminded so much of the writing prompt today for this link-up: "No matter what intends to harm you...God is never absent, never distant. You can never be undone. If God can transfigure the greatest evil into the greatest Gift, then He intends to turn whatever you're experiencing now into a gift. You cannot be undone. You, there on the edge, whispering it, defiant through the torn places: "All is grace." 
Yes I think that is what peace is; that no matter what happens, you cannot be undone. All really is grace, because if God can take the greatest evil and make it the greatest Gift...how much more would He do that in our lives?
Of course, I do not always live each moment to moment in the peace of God. But I certainly receive glimpses of it. And if I choose to whisper through it all, "All is grace," then more and more I can live in the peace of God. There are days where I am just muttering to myself, "No all is grace. All is grace. Always." 
Sometimes it feels so contradictory to sings Christmas carols of love, peace and mercy mild. Because often in life I don't feel that way and certainly the world at large does not look like that.
But then I have to remind myself peace is not about a feeling, but its about a Person. And that Person didn't promise us it would be easy. He promised that no matter what happens in our lives He would be with us, His peace can always be found and experienced.
All is grace. All is grace.  And Peace, true peace, can be found. 

Is peace a difficult concept you have had to wrestle with in your own life? Is it just me? ;-) How was your understanding of peace and God's peace grown and changed over your life?
