It is Hillary Scott from Lady Antebellum and the Scott Family's song Thy Will.

Oh how this song can be applied in so many areas in life. I'm sure for each of us, it holds a different purpose and a different meaning, but one thing I know is true-- we have all pleaded with God for something. And sometimes, the most peace comes when we say "Thy will be done."
Until Next Time,
Much love, Reba
