When the prophets say “Thus says the Lord”,they are writing from God’s perspective. If you think that they were writing from a human perspective,then you don’t really believe that God’s Word has spoken through the prophets.
The biblical writers reflect all sorts of presuppositions of their time and place that we now recognize as outdated: (1) a geocentric cosmos in Joshua 10:13;
Joshua 10,13 doesn’t presuppose a geo-centric universe.
(2) a patriarchal culture when Lot handed his daughters over to be raped by the mob in Genesis 19:8;
Lot did not,in fact,hand over his daughters over to the mob.
Two angels were with him,and they would have prevented anyone from harming his daughters.
Scripture does not record Lot’s offer as something to be approved of,but just as a fact.
(3) a flat earth view in Genesis 6-9.
Scripture does not say that the earth is flat. Anyone who speaks of North,South,East and West can be said to hold a flat earth view,because we experience the earth as flat.
Biblical hermeneutics has always had to distinguish various senses of scripture; in fact in medieval exegesis four senses were noted: literal, allegorical, moral, and mystical. Obviously the Bible’s authors were not writing literally when they referred to God in exclusively male terms, since God has no Y chromosome or male reproductive organs. So they were referring to God’s masculinity allegorically, or morally, or mystically, rather than literally.
They referred to God as a He because that is how God has revealed himself,and that is how God wants to be spoken of.
It wasn’t their choice. The Hebrews were descended from pagan Amorites and Hittites,and they were inclined to backslide into paganism,so if the prophets were writing from a cultural perspective,they would have been prophets of paganism.
