divine secret service

I watched my friend come out of a church service one time, and he shook hands with the pastor like always.Well, the pastor this time pulled him aside and said "Jonny you should join the Lords Army." Jonny replied "But pastor I'm already in the Lords Army." The pastor asked " Then Jonny, why so I only see you on Easter and Christmas?" Jonny whispered" Because I'm in the secret service."
