Chapter 9 of “Gunning for God” contains Lennox’s final reflections on the material he has been discussing.
According to the Bible, God reveals his existence to all people in two ways – through the created world and through our moral conscience. For those who have access to the scriptures, a third way is added, namely, the revelation of God which they contain.
The New Atheists lock the doors irrationally against the first. “They openly confess that they are not prepared even to listen to arguments that go outside the bounds of their naturalism. Of course it is honest of them to say that they have decided to imprison themselves inside the small world of their naturalistic castle. But whether that attitude is reasonable, or whether there is a world outside that they have put beyond their own reach, is of course quite a different matter” (Lennox, 2011, p. 229).
As cited by Lennox, Oxford philosopher J. L. Mackie, an atheist, admitted: “If there are objective values [of morality], they make the existence of a god more probable than it would have been without them. Thus we have a defensible argument from morality to the existence of a god.” (Lennox, 2011, p. 229). The New Atheists fail in the attempt to find a naturalistic ground for morality, but remain irrationally resolute against finding it in God.
Lennox does not discuss any further here the New Atheists’ rejection of Biblical testimony, but it is obvious from the previous chapter that they lock the door against this possibility, too. They do so by their question-begging refusal to accept as a reputable authority anyone who does not share their own naturalistic presupposition.
Lennox’s closing words are these” “Atheism has no answer to death, no ultimate hope to give. It is an empty and sterile worldview, which leaves us in a closed universe that will ultimately incinerate any last trace that we ever existed. It is, quite literally, a hope-less philosophy. Its story ends in the grave. But the resurrection of Jesus opens the door on a bigger story. It is for each one of us to decide whether it is the true one or not” (p. 231).
