Let me give you a little testimony of how tract ministry can reach people for Christ. When I was about 14 or 15 years old I lived in Germany and back then I was still lost. One day I rode to town on my bicycle to buy a couple of things. It was a hot summer day. I had to stop my bicycle at a red traffic light when a car pulled up beside me at the traffic light and a woman rolled down the window of the car and handed me a Jack Chick tract that dealt with the subject of the truth of the Biblical creation account. The woman in the car started talking to me about how evolution was false deception and how I could go to school and point out the errors of evolution by using this tract and becoming a Christian. It was an inspiring but short conversation. The traffic light turned green and we parted. Back at home I read the tract and was amazed at the facts it presented as evidence for creation. Something I never heard in any public school biology class. I did not understand what it meant to be born again because I was raised Catholic. But the message within those few pages impressed me and it never went out of my mind. I liked the idea of going to school and pointing out all the Bible truths about creation and other issues like the woman in the car suggested. Though I was lost at the time she saw me as a possible born again, Spirit filled believer who stands for the truth. I got saved several years after that when I heard the Gospel again on a Christian shortwave radio station. I believe that tract I received from the Christian lady in the car prepared the way for my salvation later on. So if your tract ministry does not produce qick results, then they still may come years later like in my case. This lady does not know what ever happened to the boy she gave one of her tracts. Many people who pass out Christian tracts don't know what happened to the people they gave to. But we will see the real harvest of souls when we are in Heaven.
