I appeal to you therefore, brothers,by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship.  Romans 12:1 ESV

This verse connects the body and spirit.  Presenting the physical is the spiritual act.  In mistreating my body, I am abusing worship.

Thinking this way changes the way I think about eating.  Is what I'm putting in my mouth right now, "right worship?"

That's a big responsibility - it puts eating wrongly in the category of "sin," by worshiping wrongly with my body.

The daily reading for yesterday in "Everyday Prayers" was about serving God, not man.  The author applied it to service, I applied it to my eating.  And it hit me in a good (effective) place.

Oh, the hope this gives me— the invigorating, liberating, consecrating hope this generates as I begin my day. It’s why this admonition from Paul feels more like a kiss than a kick today. I want to work more heartily at all things because of your finished work on the cross, your present work in the world, and your future work in the new heaven and new earth. Even in eternity you will shepherd us and lead us to springs of living water (Rev. 7: 17). No one will ever outserve you, Jesus.

Therefore, here’s my cry: continue to free me from doing anything for the approval of people, out of the fear of people, or to gain power over people. I work for you, Lord Jesus, not for mere men.

A frustration at work can equal "stress eating" - am I eating for the Lord, or am I eating for that co-worker?

I'm working toward a goal for my wedding.  Am I eating for God?  or for that wedding dress?  Oh...the wedding dress is a good goal!  And it's not as if we're not to have goals for this world.  But eating for the dress, to the exclusion of eating for God...is putting worship in the wrong place.I can "tag" eating as both worship, and dress.  Both apply, both work, both are good.  but in the "word cloud" in my brain, with word is largest?
And I will fail at this!  Over and over, I will fail.  But along with this failure is hope, because even the failure reminds me of the gospel. If I work/eat for God, it's because of Christ's work on the cross.

How I praise you, Jesus, that the gospel is the end of any sense of a wage-earning relationship with God. I work for you because you first worked for me. (What a humbling, staggering, and astonishing truth!) I serve you because you ever live to serve me, as my advocate and intercessor. Indeed, I love you because you first loved me and gave yourself as a propitiation for my sins. You are always first and last— the Alpha and the Omega. I’ll receive an inheritance only because of your work, not mine. And should I receive any rewards or crowns, they will be thrown at your feet, giving credit where credit is due. I pray in your quintessentially glorious name. Amen. ~~Everyday Prayers, March 20
