My guess is that Ray Comfort is a Jew with Christian doctrine, and so his understanding on Law seems to come from a Christain perspective slightly more than a Jewish one. However, I thoroughly enjoyed his insights on Law as related to evangelism, especially his research/quotes from the famous historical evangelists/teachers - Spurgeon, Finney, Whitefield, Pink, Edwards, CS Lewis, Tozer, etc. who agreed that the Law MUST be used in conversation with sinners. He emphasizes, as did others historically, that until the sting of sin and eternal damnation is felt - and felt as sin against God and not just man - then the grace message is inappropriate to bring forth. So not only is the love message in itself incomplete, but it's secondary to the message of the wrath of God in chronological order to how we need to experience God and His Word. May we each see the reality of our own humanity, and potential for sin to fall away from Him and into eternal damnation, in order to prevent an arrogant undertone when discussing Law/sin/hell with unbelievers.
What do You think about Revival's Golden Key (2002)?
