"A pastor went out" joke

A pastor went out one Saturday to visit his church members.
At one house, it was obvious that someone was home, but
nobody came to the door, even though the pastor knocked
several times. Finally, the pastor took out his card, wrote
"Revelation 3: 20" on the back of it, and stuck it in the door.
Revelation 3: 20 --
Behold, I stand at the door and knock. If anyone hears
my voice and opens the door, I will come in to him and
dine with him, and he with me.
The next day, the card turned up in the collection plate. Below
the pastor's message was the notation "Genesis 3: 10."
Genesis 3: 10 --
I heard your voice in the garden, and I was afraid
because I was naked; and I hid myself.
