In the beginning God created the heavens and the earth.Genesis 1:1 — Modern English Version (Thinline Edition.; Lake Mary, FL: Passio, 2014)
In the beginning God… There is no other objective foundation for thinking critically. It is a standard that is external to anything that exists in our reality.
With this foundation, it is easy to explain anything coherently.
To reject this foundation is to start from some personal experience in an attempt to explain reality. That is, to observe something and then try to explain its existence by working backward. One may arrive at an explanation, but it is just that… An explanation. It most likely would not ever be the explanation. In working backward, there could be a myriad of explanations, but none would be sure, objective, and true.
It is impossible to truly understand reality without the foundation, “In the beginning God.” He is the beginning of reality, He causes it to be, and continuously upholds reality. Anything that denies this isn’t true.
