Culture war defense

Had someone on our RCA email list argue against Christians fighting culture wars, since they so polarize us. Here was my response.

How are we to understand 2 Cor 10:3-5, if "culture wars are pointless"?

"For though we walk in the flesh, we do not war according to the flesh. 4 For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, 5 casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ."

I agree its sad that Christians get divided among themselves; we should be presenting one witness to the world to fulfill this text. But that division requires closer attention to the Text, not withdrawal right where the world needs Gospel Light the most.

A lot of this depends on the issue, I suppose.
- If you're referring to saying "Merry Christmas," I largely agree with you. (A rather unsatisfying victory in the culture war, when I got a "Merry Christmas" from the Barnes&Noble cashier 2 weeks ago; but a serious victory nonetheless - they acknowledged the reason for the season, whether they knew it or not.)
- If you're referring to unjust/immoral laws our nation has passed, I'd have to demur.
