As a young preacher, my small church had limited facilities, so we held baptisms in a creek. With alligators in the area, however, that was less than ideal.
Then a minister friend suggested I bring my next group of baptismal candidates to his church for a joint baptismal service. Naturally, I accepted.
The baptismal pool had a clear front so the congregation could see everything. When the baptisms were finished, curtains were drawn, and I was left alone in the pool for a moment. The building had no air conditioning, and it was quite hot. I thought how nice it would feel to take a little dip. I glided to one end, turned, and backstroked to the other end.
Hearing a riotous uproar in the church, I looked toward the congregation. The curtain was down only to the top of the glass! An astonished and amused congregation had been watching my every move.
