Scripture is the inspired Word of God, but it is always written in a human tongue. People do not speak God’s language, or have God’s knowledge, so God, when speaking to people through inspiration, must employ the human language of the culture and time of the one inspired, in order to impart any knowledge at all. God always “talks down” to us, and our finite human capacity always limits how well we understand the infinite God, and express that understanding. One cannot put the ocean in a bottle; and new wineskins must be used for new wine. As Jesus himself would later say, “I have many things to say to you, but you cannot bear them now. But when the Spirit of truth comes, he will guide you into all the truth.” (John 16:12-13)
The inspired recipients of God’s word in Genesis believed the sky to consist of a dome, in which the sun, moon, and stars were set, and which had windows to admit the rain stored in the pool of waters above. God, of course, knew that this was not true, literally or in any other sense, but the minds of those God inspired could have no place to hold such concepts as gravity and freely floating planets, stars and moons — or that the earth was not stationary at the center of a revolving universe. They had the evidence of their senses to the contrary, and would not, as Jesus would later say, have been able to “bear” the truth. So God communicated to them in a language that did not seem outrageous to them, that met their expectations, and explained and ratified what they perceived. The primary truth God intended to convey, after all, was not a literal account of the composition of the cosmos, but the theological principle that God is the creator of all that is.
In the same way, the accounts in Genesis 2 through 4 do not present a literal history of the first human beings, but a theologically relevant account, God’s word designed to explain truths to people in keeping with what they perceived, within their time and place — to address the really big questions to which the account provides the answers: primarily, why is it that people do wrong things; why do they die; why do they marry; and why should a perfectly natural thing like childbirth be so painful.
