Do you remember tracts?
If you have never heard of them, they are small items that contain the gospel message.
They are usually on one sheet of paper or less. They may be as small as a 3 X 5 index card.
The idea is to have something which is not bulky and which is easy to carry, with the gospel message, to hand to someone.
Here are some tracts you can use. They are free to print and give away. You can download them, print them, and give them away, but you cannot sell them.
