Romans 10, NASB
8 But what does it say ? "THE WORD IS NEAR YOU, in your mouth and in your heart " - that is, the word of faith which we are preaching,
9 that if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you will be saved;
10 for with the heart a person believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation.
If that's not a "sinner's prayer," I don't know what is.
John 4
28 So the woman left her waterpot, and went into the city and said to the men,
29 "Come, see a man who told me all the things that I have done; this is not the Christ, is it?"
30 They went out of the city, and were coming to Him.

41 Many more believed because of His word;
42 and they were saying to the woman, "It is no longer because of what you said that we believe, for we have heard for ourselves and know that this One is indeed the Savior of the world."
The first instance of friendship evangelism recorded in human history, and it's in the book of John.
While I admire Kirk Cameron and Ray Comfort's methodology, it isn't new, and there are very few methods of evangelism that don't challenge a person's better view of themselves than Christ has. You seem to think Way of the Master is the end all and be all of personal evangelism. It isn't. It's good, no doubt. But there are other methods equally effective, and to call them "unbiblical" simply because they don't specifically and formally address sin through the Mosaic Law is absurd.
Then there are those who are overly critical of others, think they have all the answers, and believe the only "right" way is their way. Perhaps you can explain to me why
that happens?
The mistake you and others make, who criticize these allegedly "quick decisions," is that those who make those decisions have been thinking about it for some time. Otherwise they wouldn't be in a place where the could hear the truth, feel the work of the Holy Spirit upon them, and once and for all make that decision. While I understand our Pentecostal brothers and sisters are guilty of emotionalism whipped to a frenzy to "force" an on-the-spot decision by people who previously haven't thought about their need for salvation (and at that point haven't really made a decision anyway), rarely are there "quick decisions" made when proper evangelistic efforts have been exerted. It is simply a matter of one "reaping the harvest" after a chain of 15, 20 or a hundred people who have planted a seed, watered, fertilized, encouraged along the way. To claim these to be "quick decisions" is to utterly fail to understand the process that God brings a believer through before their actual salvation.
And whose counting heads now? Keeping a tally of "how many I've led to the Lord" doesn't appeal to me. It isn't a measuring rod of my "righteousness" or "engagement in God's work." It isn't even me who did it. I simply speak words. God does the work. Counting heads is an egocentric method of "counting sheep" that removes Christ from the throne and puts me on it. No thanks.
