The phrase "presuppositional apologetics" might be lost on many in the church, but its method and use has continued to increase in popularity even today. Dr. Bahnsen didn't develop the method but he did give it teeth, as demonstrated remarkably in his formal debate ("The Great Debate: Does God Exist?") with Gordon Stein as well as several other debates.
Yet he not only demonstrated this method of defending the faith, but taught it to thousands in the church. And his legacy continues today through various means.
While I have my own project in passing Dr. Bahnsen’s legacy on to another generation by converting several of his lectures into book format, there is another project from a separate ministry for which I highly recommend your support in both prayer and funds. Their goal is to make all of his “audio lectures, courses, syllabi, and position papers available to the public free of charge." You can find out more about it here: https://bahnsenproject.com
Please do yourself a favor - do the church a favor - if you haven't heard of Dr. Bahnsen, acquaint yourself with him. Listen to one of his lectures, sermons, or debates, or read one of his books. You won't walk without having grown in your understanding of the Scriptures.

While not an exhaustive list of his books, his works include (some published post-humously):
Consider reading one of them. And maybe even more importantly please, please consider supporting my friends over at the Bahnsen Project ministry to help make his lectures free of charge for all.
