Think of an achievement you can do to set a world record (even if it’s
only a world record in your own opinion). Make the world’s biggest
offering bag, play the most verses of a hymn without stopping, letterbox
the most houses in an afternoon for a church program, recite the books
of the bible the fastest (forwards or backwards), find the most
different animals inside an hour, or think of you own idea. It could be done on your own but even better to include many people, or as a fund raiser for a church project.
