"attributes of God" NEAR rational doesn't find any Bible references although it does find an interesting discussion by Strong. I assume that I'm not using the right buzzwords.
I'm trying to find a Bible reference to support "God is rational ...", the first words of the Preface in Geisler, Norman L., and Ronald M. Brooks. Come, Let Us Reason: An Introduction to Logical Thinking. Grand Rapids, MI: Baker Book House, 1990.
Nothing exciting, just gathering info for a review
