7 Ways to Kill the Thanksgiving Impulse in Your Life

“Let your reasonableness be known to everyone. The Lord is at hand; do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus.”
– Philippians 4:5-7

This is an excellent recipe for what it itself describes: a Spiritual settling of the heart, thankfulness, closeness to God. But let’s suppose you didn’t want those things, you didn’t want to be thankful in all circumstances (as God commands through Paul in 1 Thessalonians 5). How would you design your system in order to crush any impulse of thanksgiving in your heart?
1. Freak out about everything.
Let your unreasonableness be known to everyone. Be unreasonable about everything. Turn everything into drama, everything into a crisis.
2. Practice practical atheism.
The Lord is at hand, which is certainly something to be thankful for. Our God isn’t just transcendent, but immanent. He wants to be known. You could therefore intellectually acknowledge God is there, but act like he’s not. Assume he has no interest in you or your life. If you pretend like God’s not there, you don’t have to thank him for anything.
3. Coddle worry.
Be anxious about everything. Really protect your worry from the good news.
4. Give God the silent treatment.
The best way not to give thanks is not to talk at all. That way you’ll never give thanks accidentally.
5. Don’t expect anything from God.
Don’t trust him for anything. Normally we do this so we don’t have to feel disappointed, but another reason to do it is so he won’t give you anything to be thankful for. If you pray for something, he just might say yes, and then you’d be obligated to thank him.
6. Relentlessly try to figure everything out.
The peace of God is beyond our understanding. He is bigger than our capacity to grasp him. The closer we get to God, the bigger he gets. An immense vision creates immense reaction. So if you want to crush that reaction before it has a chance to start, ask as many “why” questions as you can, and don’t settle for the answers Job or Habakkuk or David did. Best to think you’re better than them and deserve an explanation from God. If you really want to kill thanksgiving, act like God owes you. Leave no room for the possibility you might not know or understand something. And one of the best ways to crush thankfulness is to take credit for everything you can.
7. Focus on anything other than the gospel of Jesus.
God owes us nothing but has given us every good thing in Christ. If you’re not interested in thanksgiving, by all means, pay no attention to that. Concentrate on your problems. Don’t concentrate on Jesus, or you might accidentally end up thankful in all circumstances.
