God expects us to care about the details of our life. It's in the Bible, Luke 16:10, NIV. "Whoever can be trusted with very little can also be trusted with much, and whoever is dishonest with very little will also be dishonest with much."
Little things are important. It's in the Bible, Song of Solomon 2:15, NIV. "Catch for us the foxes, the little foxes that ruin the vineyards, our vineyards that are in bloom."
