BX442: Boom! With an exclamation point

[shernren]

That's the whole point. We don't draw the line, we allow scripture to draw it. Scripture uses the term day is several ways, and its meaning is determined by usage. We do that same in english.

In my grandfather's day, he walked to school and back every day, and always made it home before the day's end.​

It's crystal clear what the term "day" means in each usage in that one sentence. Same is true in scripture. Now I suppose someone could take that sentence and make an argument for other definitions of the word in each case, but it would be silly.

But did your grandfather actually walk to school and back every day? (I know mine probably cycled, for example.)

If not, then you have just demonstrated that a sentence in which every literal and metaphorical use of "day" is clearly demarcated may nonetheless not only be wholly non-historical, but be said for a completely different purpose from what its "grammatical-historical interpretation" may mean. After all, you didn't write that sentence to tell us your grandfather walked to school, now did you? You wrote it to (try to) teach us about literal and non-literal interpretation. And all without a single accusation of lying in sight.

Language is far more complex than you realize, and context is king - the context in this case including the context God has provided for us, namely the universe He is actually describing.
