I am not my own.

All my hope is found in that I am not my own. 

My hope for today is that I am owned. 

The Heidelberg Catechism begins with this question & answer:

Q & A 1

Q. What is your only comfort

in life and in death?

A. That I am not my own, but belong—body and soul, in life and in death—to my faithful Savior, Jesus Christ. He has fully paid for all my sins with his precious blood, and has set me free from the tyranny of the devil. He also watches over me in such a way that not a hair can fall from my head without the will of my Father in heaven; in fact, all things must work together for my salvation. 

Because I belong to him, Christ, by his Holy Spirit, assures me of eternal life and makes me holeheartedly willing and ready from now on to live for him.

If I am my own then my sins are still mine. If I am my own then I'm still under the tyranny of the devil. I must never rest if I am my own, for who will watch over me? If I am my own, who will ensure that this day, or any day, will be for good? If I am my own, then I am the most pitiable of all people. 

All those who are "their own" are then subsequently "on their own". 

What joy, hope, wonder, and amazement is this! That I am not my own, but belong, the whole sum of all that is me - to the resurrected reigning Lord Jesus Christ. Nothing he owns comes to ruin, but it all comes to joyful fulfillment in him. I am not my own, I am not alone. I am His, and He is mine.
