I will keep this simple. Colossians 3:17 tells us, "And whatever you do, in word or deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him."
1 Corinthians 10:31 reminds us, "So whether you eat or drink, or whatever you do, do all to the glory of God."
Similarly Romans 14 constantly reminds us that food could destroy the work of God if eaten in a way that is not humble or driven by the love of Christ.
These verses collectively lay out some really good principles of Christian living.
1) All things we do are spiritual and therefore should reflect the gospel.
2) This means that what we eat is ultimately a gospel issue if done properly or improperly.
3) If you ate at Chick-Fil-A (CFA) today, then fine. How did you eat there? Did you eat with a spirit of humility? Did you eat with a vindictive spirit? Was your goal to "take a stand for Jesus" (how does eating a chicken sandwich do that again?) or was it to glorify God (which by the way, you should be seeking to do tomorrow as well)? Did you eat there because you are against others or did you eat there out of a spirit of compassion and love? Did you cause any fellow brothers or sisters in Christ (maybe those struggling with homosexuality) to stumble in their faith by eating there? Did you eat in a self-righteous manner and attitude? Did you give thanks to God as you ate there? Did you overeat while you were and so disobey God by being a glutton? Just some questions to think about....
4) If you didn't eat there today, did you refuse to do so because you felt other Christians were being immature? Did you pass judgment on your brother or sister in Christ for doing that (and so violate God's Word)? Did you act in a self-righteous manner because you felt you were somehow being a "cool Christian"? Did you show love to those who differed in opinion from you or did you try to shame them? Did you love Christ and glorify Christ in whatever you did choose to eat instead today? Did you bring glory to Christ in NOT eating there today? By not eating there, did you cause any fellow brothers or sisters in your church to stumble in their faith?
Here is how it worked out in my own life: I wasn't going to eat there simply because I didn't care and I didn't see how it was going to legitimately advance the Kingdom. However, Sunday, one of the members of my youth volunteer team asked if we could order CFA for our ConXion night this Wednesday.
I love CFA. I appreciate the stance the CEO has taken on this issue. I love my church and I know several people from my church were wondering what stance I would take. Since I knew that I could eat at CFA or not eat at CFA and still glorify God either way, I opted to eat there. I used this time to teach our youth that it is more important about what we are for than what we are against. I think we also should encourage people (even CEOs) when they take a stand for what we approve of.
I had to confess to God though that I had a very self-righteous attitude when I saw how many people were in CFA. I thought to myself, "Most of these people are probably here for the wrong reasons." Then I realized I was being self-righteous and judgmental. I realized that ultimately, it is by God's grace that I can eat and that I should give thanks for CFA and the opportunity I had to eat there today.
So I ate at CFA and enjoyed the gospel...not because buying a chicken sandwich made me holy or righteous (something I by virtue of being united with Christ), but because I strove to eat for the glory of God.
