Yea man I get it, I've seen baptist jump with joy and count every Prayer as a salvation. But I know from personal experience, when they don't pray, its because something is holding them back, I know because I ask them, and then they usually tell me what it is, and we address those issues. As long as seeds are planted, God can give the increase. if a seed just sits in a seed vault, its not going to grow.
Even if people were out there doing this, and maybe rushing into the prayer, I'd rather have people out reading the Bible to unsaved, than sitting on their butts just talking about it. You can't get better without practice.
We've seen people say the sinners prayer, and a week later, pick them up for church, and deny Jesus right in front of us. one example was the husband and wife, we "led them both to the Lord". the Husband rejected Christ later on, but guess what, his wife was coming to church everyday after that. So who cares, if people want to count a prayer as a salvation, Jesus does the work, and gives the increase, and some seeds will grow and we will never get to meet that person. Which is sad, but for all the ones I do get to meet, if I get to meet 1 out of 100 and watch their life transform, thats worth it.
I wouldn't be out doing this if I thought it wasn't working, trust me, I have much better things to do on a Saturday, Sunday, or week day, Sad to say, but if I did not see the fruit grow, I probably wouldn't be doing it at all... which means my faith in God's commandment to GO wasn't there to begin with. Luckily, he showed me people being reborn, and thats why I will do anything to get this message out, including any type of legal ramification you guys accuse of (this was all checked out legally btw).
We could also go out like Ray Comfort does, who is not signing release forms but doing it through the video itself, I guarantee you none of those people want to be on video, and its full HD of their faces, especially the ones that are being embarrassed or made fun of because they are dumb atheist/scoffers.
