You're not Yours
"...ye are not your own...ye are bought with a price" (I Corinthians 6:19-20)
This might hurt. If you're not yours, you have no rights. That means that you don't have the right to make your own decisions! It is your responsibility to see what your owner wants, and to allow Him to make the decisions. This applies to everything!
Here's an example of where it hits me: when I want to stop and spend $1.29 for a cup of coffee, it is my duty to discern whether that cup of coffee is God's desire, or just mine. Sound extreme? It is.
But I am either bought with a price, and not my own, or I am my own, and I am not His. It's one way or the other. I can't serve two masters, and I can't have two owners. It's that simple, and that extreme.
Where is it going to hit you?
