Carrying around little Gospels of John is a wonderful way to share your faith. They are offered by the The Pocket Testament League for a donation of $20.00 for 30 copies. See a few of the over 80 different covers below.
You can also choose different translations. I use the New International Version.
After I verbally share my faith, if I sense that they are interested, I then give them a Gospel of John. I have stickers that I put on the back of the Gospels that has contact info so they can call or email me. Also, I put my church address and service times on the sticker. I only give the Gospels out to those who show interest in Christ, otherwise they will trample Him underfoot. Think: Pearls before swine!
I once gave them to some Jewish guys. They were in their car ready to leave, so I handed them each a Gospel. As they drove away they tossed them out the window!
One caution! I tear out the first 3 pages because it contains an easy-believism, man-centered Gospel message. I also tear out the second to last page; read it and you will know why.
This makes for a great gift; people actually appreciate them. Someone gave me a Gospel of John a few months before I was saved over twenty years ago. I think I still have it among my memorabilia.
