I had to go to the post office to mail some tracts to new tract club members. Since I had a nunber of envelopes that were all the same, the clerk asked me what I was mailing.
Wow! What a great segway to the Gospel.
So I said, “gospel tracts!” and reached in my pocket and handed her an Are You Lucky tract. She immediately read the front and then turned it over. Realizing there was a lot to read she set it aside and said she would check it out after work.
Now I realize that unless you were mailing multiple envelopes of tracts, the exact scenario might not apply. However, with any number of questions in a short dialog with the clerk you too could leave a tract with the postal clerk.
On a side note, at the post office, they ask if the packages contain anything fragile or harmful. I could say something like, “no, contents may prevent eternal death” or “no, contents promote life!”
