The way that I know Christianity is true is first and foremost on the basis the
witness of the Holy Spirit in my heart. This gives me a self
authenticating means of knowing Christianity is true wholly apart from the
evidence. And therefore, if in some historically contingent circumstances,
the evidence that I have available to me should turn against Christianity.
I don’t think that that controverts the witness of the Holy Spirit. In
such a situation, and I should regard that simply as a result of the contingent
circumstances that I am in, and that if I were to pursue this with due diligence
and with time I would discover that in fact that the evidence—if I could get the
correct picture—would support exactly what the witness of the Holy Spirit tells
Apologists are always claiming that they just follow the evidence wherever it leads, but in fact, the rule for Christians is: Follow the evidence whenever it leads to Christianity; otherwise follow your subjective feelings.
