There is a logical explanation.

 What in the world is this? Didn't this thing just get thrown away? Did not the garbage man take the garbage away and put it in the sanitary landfill (which is so much better than an unsanitary landfill). So how was it back in the mail.

Tearing the envelope open, not waiting this time, you rip the outer envelope. There inside was the obligatory inner envelope holding the invitation. On the outside of the envelope it read, "Why did you throw my invitation away?" Shaking your head in wonder, you think to yourself, who is doing this? More than that, why are they doing it.

Wait. You now get it. It is your wife. She is the one doing this. After all, who else knew that you threw the invite in the garbage? She is behind this very thing. You are going to confront her when she gets home. At least you got to the bottom of this mystery.

A little later, you hear the garage door open. With a smirk on your face, you wait for her to walk into the house. As the door opens, you look over at her. "What is up?" she asks as she walks in. Holding up the invitation, you tell her, "You are busted. I know what you are doing." She looks at you for a moment, then a smile breaks out on her face. "Really? And what is that you are holding?" 

"The invitation that you pulled out of the garbage and put back in the mail. You are the only one who could have done this." Walking over, she took the invite from your hand. Looking at it, she reads it, and then, reaching into her purse, she pulled an invitation out of her purse. "You mean this one?" she asks. "I took it out of the garbage. I wanted to hold onto it. I showed it to my hairdresser. We talked about it and wondered what it means."

Looking at her, you take the invite out of her hand. Looking at it, you realize that it is the one you put in the garbage. There are the stains from the garbage on it. Looking from it, to the new one, you are confused. What is going on? How did this one get here? "You didn't send it?" "No I did not," she replied. 

Setting down the original invitation, you take the new one, open the inner envelope, and pull out the invitation. Looking at it, you read, "You are still invited. The invitation is still open for you to come to worship with your family." That is all it said. Really? What is this? Who sent it. There at the bottom is the same thing as the other invitation...

your Father, God.

So there it is again. Is it really from God? Could it be?

Then you had a thought, where is the envelope? There would be a cancellation on the stamp. Picking up the pieces of the envelope, you put it together. The stamp was a Christmas stamp. The postmark was, what? Heaven. Really? Heaven? No state. Just heaven. That is not possible. 

Showing it to my wife, I looked at her questioning. Her eyes grew wider. Looking at me, she said, "Could it really be from God?"

I did not know.
