Sabbath Day Scribblings - Who defines you

Men sometimes identify themselves by titles, observed President Dieter F. Uchtdorf, who then went on to suggest the titles he believes apply to all priesthood holders in the Church.

"One title that defines all of us in the most fundamental way is 'son of Heavenly Father,' said President Uchtdorf, second counselor in the First Presidency. "No matter what else we are or do in life, we must never forget that we are God's literal spirit children. We were His children before we came to this world, and we will be His children forevermore. This basic truth changes the way we look at ourselves, our brothers and sisters, and life itself."
Knowing that, yet coming up short sometimes, can be discouraging, he acknowledged. "The adversary likes to take advantage of these feelings. Satan would rather that you define yourself by your sins instead of your divine potential. Don't listen to him."

This is the very beginning of his talk, and I loved reading the highlights this morning.  So, who defines you in your own life?  Is it your Father in Heaven, who knows you and loves you in spite of yourself?

Or is it Satan who wants you to define yourself by your sins instead of your heritage?  Who we are, seems to depend on how we define ourselves.
