This is a message delivered at the ‘God’s Not Dead Conference’ in San Diego, California. Pastor Jeff Durbin of Apologia Church in Arizona presented a sermon on Presuppositional apologetics.
The Youtube page has this description:
In this message Jeff provides the foundations for demonstrating that the God of the Bible is the necessary reference point for truth and that apart from the Trinitarian God of the Bible you fall into foolishness.
I’ll have to watch this later and is one of a few links I’ve “filed” for after VBS this weekend.
