Gerstner makes many comments about apologetics. But some of his assumptions do not account for what has been learned in computer science and information theory.

"What the finite mind ultimately comprehends is the finite, never the infinite, a seemingly commonsense connection". Gerstner, J. (1996). Primitive theology: The collected primers of John H. Gerstner. Morgan, PA: Soli Deo Gloria Publications., p. 15.

This claim is contradicted by modern computer science. Computer science can be defined as the search for finite representations of infinite (or potentially infinite) objects. The more finite the time, the faster the program runs. The more finite the space, the less memory it takes. And so on.

Such reasoning and application is done all of the time in applied programming language theory, in the foundations of computing, in algorithmic information theory, and (though some programmers may not be aware of it) in everyday computer programming.

His statement right before the above statement is that "God is beyond finite comprehension" has some validity. We can never fully understand God. But we do have ways to approximate our understanding in more than just a finite way.

Isaiah invites others to join him and "reason" together.
