Getting the lens in the mail was clearly a message from God.
He wanted you to have the lens.
Now that you have foolishly returned it, you have destroyed the intended order of the Universe.
The person who will now receive the lens may take a photograph with it that he would not have taken otherwise.
Maybe the photograph will be posted online. Someone who sees it might be influenced to kill someone, or perhaps the time he spent looking at the photograph will delay him several minutes, and he will be struck by a bus because of the alteration in the timing of his final excursion.
Perhaps millions of years from now, this tiny warp in events will cause a break in the fabric of the universe. A warring tribe will unearth a time capsule with instructions to develop a biplane in an era of post-nuclear devastation and destroy the rival tribe with the last vestiges of human DNA, leading to a planet populated by intelligent reptilians who will eventually populate the known universe, and their spacecraft propulsion systems will cause a rift in the fabric of space-time.
They may trace all this to you, and return in time to punish you in ways you can't even imagine.
You were a fool not to keep that lens. You have defied the will of God, refusing his gift.
Not only that, but you have advertised that fact in a public forum.
If you have not experienced Hell before, you will likely receive a swift education.
Next time think before you pat yourself on the back and crow.
