Open Sesame

For four years I have not had a key to the deadbolt on my apartment's front door. A few times a year I ask Roger if he would find it for me. Three of my neighbors have keys that can lock and unlock it, which is very convenient when I do want to use it. However, I just wanted my own. I've been pestering Roger more and more about it. A couple of months ago he looked for the number of the key but couldn't find the key itself. Today, he finally told me which key it was. Turns out, it's the key to my classroom, which has been in my hands all this time.

I'll let you take your own spiritual application from this story. I'm sure you can find a few.
