Well first of all, The Way of the Master twists Scripture to make their point. They selectively quote and apply in specious (and spurious) ways. So you're not winning this argument with "well Ray Comfort says..." Though I'm appreciative of good efforts to spread the Gospel, and though I am wary of Comfort, I happily partner with folks who use "Way of the Master" but refuse to bow to their legalism. There isn't ONE and only one BIBLICAL method of evangelism.
I'm not spending a lot of time here but I'll toss out these examples and move along:
- Just quoting from the OT isn't inherently quoting "the Law"...especially for the first century Jew. To quote "the Law" meant you would likely refer to the Pentateuch and then Mishnah and Talmud. I don't see Comfort pointing out either of those in his text.
- Secondly, the greatest sermon given (Matthew 5-8) is entirely devoid of direct OT citations. It calls people to a new ethic and new Kingdom yet doesn't quote from "the Law" at all.
- Thirdly, notice Paul's two examples of apologetic methodology (and ultimately evangelistic call) in Acts 17 and Acts 22. In Acts 17, Paul goes to a less than public place and uses their cultural signs to proclaim the Gospel. This includes quoting from a secular poem. Yet does not directly quote from OT Scripture. In Acts 22 he never quotes the OT and preaches among Jews not on a street corner. In Acts
- Fourth, Jesus' method of "evangelism" was to call others to Himself and to follow Him while casting off their worldly ideals.
- When, in Acts, it refers to Paul (or anyone else) referencing the "Law and the Prophets" that is Luke's way of saying the Old Testament. Since it was their only testament, and thus not old yet, it isn't inherently the Law.
- I don't have to work this out, but the nature of apostolic evangelization in the first century wouldn't have been on street corners and in open air proclamations like you're used to or think that is the only method. Frankly, given the persecution ongoing in the first century most evangelistic relationships were done person-to-person by inviting them into a house church or community. The exposure to the kerygma, the early preaching of Christ, was done personally more than publicly. We look to Paul's letters about this and think of 2 Corinthians 6:13; Ephesians 4:1-3; 1 Timothy 4:16; etc.
- Notice Acts 18:26, after Apollos had attempted to speak about Jesus he was taken into a home (not on a street corner) to be refined.
- Philip and the Ethiopian Eunuch from Acts 8:26-40 was not public proclamation but personal connection. BTW, just to point out, given Luke's understanding of the Law and the Prophets, the texts used to present the Gospel to the Ethiopian Eunuch are from the Prophets and not the Law.
- Also, in looking at Jesus' specific way of spreading the message about His own messianic mission, the Gospels seem to be taken with the reality that he did so by performing miracles, casting out demons, and healing people. I'd point to Matthew 4:23-25 and Mark 1:21-39 specifically.
I can go on but this is a start.
