Some clever soul winners have organized a set of foreign language tracts so that they will have them available when they meet someone who speaks that language. One placed stacks of tracts in a large box in his car so he could show it to the person and let them pick the language that they recognize.
Another had a smaller box with dividers labeled with the different languages. Still another put them in alphabetical order in bags with the stapled edge sticking out where the language is printed. He would thumb through them until he found the right language.
Another fanned a handful of tracts like playing cards and asked if the person recognized any of the languages. When you have a tract in their native language, their surprise guarantees that they will take it —and you have delivered the gospel again.
