Too often I'm guilty of eating without thinking. Grabbing something that's next to me and chowing down without any regard to what the food is, how it's going to make me feel, or if it's good for me in the long run.
Jonathan Edwards actually took the time and energy to keep track of what how different foods made him feel.* (And this was before smart-phone apps!) His goal? Eating food that didn't slow him down and helped him feel better would allow him to serve God more effectively.
It's not too often you read about gastrointestinal spirituality, but maybe hearing about it every once in a while is a good thing.
Some questions to ponder:
What are you eating?
How does it make you feel?
Are you being intentional with your food choices?
