What does it say about someone's faith that they need a baking sheet to be reminded of God? And you're assuming without a shred of proof that God is behind a food stain on a baking sheet. Now if you pointed to a rainbow or the intricacies of a tree I'd say God's hand is evident...a baking sheet...sorry, no.
If God dropped a Duesenberg in your back yard from the sky, would you be awed and be interested in keeping it or at least showing it to tell people how God had interacted with you? Or would you just discard it as "just another object"?
Without a doubt, that is the most bizarre question I've ever been asked on a message board. I'll let you know once a Dusenberg drops in my backyard...until then it remains just an irrational question.
What does it say about someone's faith that even so mundane an object as a baking sheet reminds them of God? Matt. 18:2-4
And how is any "natural" thing evidence of God?
How is my question irrational, any more than your rainbows as "evidence of God"? Wouldn't you want to keep "keepsakes" of people you love, much less something you got from God? I suppose the Jews are fools for "venerating an object" like the Ark of the Covenant.
I'll also bet you don't know what a Duezie is. I just used that so that something mundane like a - oh, well, a cookie sheet - wouldn't be disparaged easily as an "unlovable" object easily discarded. But it could be either way. If I had a rose given - actually GIVEN, not just your "nature" that I found on a walk - by God, I'd keep it.
