If there is no God, then man and the universe are doomed. Like prisoners condemned to death, we await our unavoidable execution. There is no God, and… - William Lane Craig

The Bible says all men are without excuse. Even those who are given no good reason to believe and many persuasive reasons to disbelieve have no excuse, because the ultimate reason they do not believe is that they have deliberately rejected God's Holy Spirit.

What can we say about metaphysical naturalism? Again, I want to make two points.

We've already said that it's the Holy Spirit who gives us the ultimate assurance of Christianity's truth. Therefore, the only role left for argument and evidence to play is a subsidiary role. I think Martin Luther correctly distinguished between what he called the magisterial and ministerial uses of reason. The magisterial use of reason occurs when reason stands over and above the gospel like a magistrate and judges it on the basis of argument and evidence. The ministerial use of reason occurs when reason submits to and serves the gospel... Should a conflict arise between the witness of the Holy Spirit to the fundamental truth of the Christian faith and beliefs based on argument and evidence, then it is the former which must take precedence over the latter, not vice versa.
