Douglas Groothuis, Christian Apologetics: A Comprehensive Case for Biblical Faith (Downers Grove: IVP, 2011), 329:
ID [intelligent design] should take its rightful place in the overall circle of evidence. Standing alone, it cannot provide a full apologetic for Christianity. Rather, ID provides strong evidence against the reigning naturalism in the realm of biology, as well as some support for theism as an overarching worldview.
That’s how Groothuis concludes his chapter “Evidence for Intelligent Design” (pp. 297–329).
