That’s fine, if we don’t want to give an inch, but give me an example in this day and age when such an approach worked off the bat with a nonbeliever. Heck, we can’t even get Reformed brethren from buying into cultural Marxism... we give more leeway to our own reformed brethren, maybe we need to hit them with this approach, a second time, if need be
Presuppositionlism is the only approach which starts and ends with the self-attesting Christ of the self-authenticating Scriptures and therefore the Gospel of Christ, the power of God unto salvation, is our final defense. The Gospel works as God so wills. The work of God alone made me a believer, He used the Gospel to do His work. Personally I knew nothing of formal apologetics or philosophy before the Gospel worked in my conversion.
