I have been contemplating the concept of sacrificing those things that call me away from God in favor of those that lead me to Him.
I don't think it is a one-time thing. In fact, I think it is a daily thing. Maybe even a moment-by-moment thing. Truly a "living sacrifice".

The reward is to be close to God on a daily basis. That should be enough all by itself.

So why is it so hard to do consistently? Maybe I don't like the idea of giving something up that has been a part of my life so deeply that to give it up would make me uncomfortable.

I went to a chiropractor once. He said the first few adjustments would make me very uncomfortable. My body would be out of its old bad alignment and not yet settled into its new healthy position. It wouldn't feel right, but I had to trust it until it became normal.

I think it applies here. God calls me to sacrifice "that which I cannot keep to gain what I cannot lose." I will say that many times today.
