Secret Service

I went to Easter Service at my church today., and as I was leaving. The Bishop was standing at the door as he always is to shake hands. He grabbed me by the hand and pulled me aside.
 
The Bishop  said, "Dennis, You need to join the Army of the Lord!"
 
I  said to him, "Bishop, I'm already in the Army of the Lord, "
 
The Bishop  questioned, "How come I don't see you in church except at Christmas and Easter?"
 
I whispered back, "I'm in the secret service!"
