I remember when food products had no expiration dates. We could tell when food was bad, so we didn't eat it. Actually I don't really remember finding any bad food. Apparently my parents took care of it.
Now everything has expiration dates, and it appears that (my) children consider examining expiration dates to be part of their due diligence before ingesting anything. Never mind common sense or the sense of smell. Let's look at that date.
(By the way, I have seen salad dressing on the grocery shelf with an expiration date less than a month in the future. Who uses a whole bottle of dressing in a month? No wonder they are all expired in your fridge.)
Maybe kids could trust their parents or their senses in evaluating food.
But think of the due diligence we exercise with our Heavenly Father. Yes, I know that you said to forgive, but I want to consider what that will really mean. Yes, I know that I should tithe, but how can I live on 90%? Yes, I know that you promise to meet my needs, but I'm just a worrier.
We diligently examine God's directions, wondering if he really is looking out for us. We wonder if we can trust him. So we check behind God to make sure that we can go along with his Word.
Maybe he laughs at me and rolls his eyes like I do with my kids.
