On theological but not necessarily scientific grounds. He’s defending it against Theistic Evolution: A Scientific, Philosophical, and Theological Critique, pointing to a defense by Michael J. Murray and John Ross Churchill:
One of the things I appreciate about Michael J. Murray and John Ross Churchill’s paper is their candid embrace of the label, “theistic evolution,” for their view.1 This strikes me as much more accurate and straightforward a label than the euphemistic appellation, “evolutionary creationism,” recently adopted by some theistic evolutionists, which seems clearly an attempt to coopt the label, “creationism,” in order to make their view more palatable to evangelical Christians.
It will be helpful at the outset to note the very limited scope of Murray and Churchill’s response to the volume, Theistic Evolution: A Scientific, Philosophical, and Theological Critique (SPTC). They state that the volume as a whole conveys “the message that for Christians with traditional doctrinal commitments, no version of theistic evolution that adheres largely to consensus views in biology will be a plausible option.”2 They maintain to the contrary that it is “incontrovertible” that there are versions of theistic evolution that are “immune to many of the key criticisms advanced” in the book.3 More specifically, they argue that “there are versions of theistic evolution … that are consistent with traditional doctrinal commitments” concerning divine providence, miracles, evidence for theism, and nonphysical souls. It is evident, then, that their concern is with doctrinal criticisms of theistic evolution.4
Now immediately I felt myself rather left out of the conversation. For I am a Christian with traditional doctrinal commitments, but any reservations I have about the viability of theistic evolution have nothing to do with such doctrinal commitments. My reservations are not theological but scientific in nature.William Lane Craig, “Response to “Mere Theistic Evolution”” at Peaceful Science (March 7, 2022)
Some of us would think that if theistic evolution fails a science test, one needn’t bother with the theology. But maybe we misunderstand.

But the pruning process in which he is engaged can never really stop. The “sensible God” is most likely the one looking back at us from our medicine cabinet mirrors.
