A new pastor was visiting in the homes of his parishioners. At one house it seemed obvious that someone was at home, but no answer came to his repeated knocks at the door. Therefore, he took out a business card and wrote 'Revelation 3:20' on the back of it and stuck it in the door.

When the offering was processed at the next worship service, he found that his card had been returned. Added to it was this cryptic message, 'Genesis 3:10'.

Reaching for his Bible to check out the citation, he soon broke out in laughter. Revelation 3:20 begins 'Behold, I stand at the door and knock.'

Genesis 3:10 reads: 'I heard your voice in the garden and I was afraid for I was naked.'
