I just want to share something about the pocket sized Gospel of John you get from pocketpower.org, which was mentioned above.
I ordered a few copies just to see what they were like. I thought it might be a good thing to give these away at our church's bookstore.
However, when I received them today, I was dismayed to find that there was more than the Gospel of John between the covers of these booklets.
Among other things, they contain advertisements for the Evangelical organization which runs the website, including an offer for a correspondence course. They also contain a few pages illustrating the Evangelical view of salvation. This includes an illustration showing that "good deeds," "morality." and "religion" are "the wrong way to God" and that they lead to sin and separate us from God. Now, I can understand these people saying that good deeds, etc. do not in themselves save us (We need Christ.) However, they are actually saying that they're wrong and lead to separation from God!
Needless to say, I was very disappointed. I think the idea of giving away free gospel books is great, but when you add advertising and the other messages, it really ruins it!
