---This is a deduction from the fact that he was created in God’s
image (And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth. So God created man in his own image, in the image of God created he him; male and female created he them. Genesis 1:26–27),
---and from the fact that Jesus, the Second Person of the Trinity, is the logos (In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by him; and without him was not any thing made that was made. John 1:1–3).
This ability to think logically has been impaired but not eliminated by the Fall of man into sinful rebellion against his Creator. (The Fall means that sometimes the reasoning is flawed, and sometimes the reasoning is valid but from the wrong premises. So, it is folly to elevate man’s reasoning above what God has revealed in Scripture.) ----But if evolution were true, then there would be selection only for survival advantage, not necessarily for rationality."
