You speak about “adding to the text”, but has it occurred to you that you’re doing the same thing? After all, you’re reading “now I know, since…” and you’re presuming that it means “I didn’t know before this time.” How do you reach that conclusion?
I reached that conclusion by knowing basic language skills. It’s the kind of conclusion that anyone not trying to fabricate a narrative that differs 180 degrees from the words themselves would also conclude.
“I just solved the formula.”
“Perhaps you always knew the formula.”
“No I solved it. Just now.”
“I can’t make that conclusion. Who’s to say that solving the formula says anything about not having already solved it?”
After all, it’s not just a simple “now I know,” as if God didn’t know previously. Instead, it asserts that the action itself demonstrates a fact that can be known by virtue of the action. This doesn’t imply that God was not in possession of the knowledge prior to the action.
The phrase
literally does mean that God lacked knowledge prior to now. The word now wouldn’t be used at all and neither would the “since” portion since they both tell the reader/listener that there is a dilenation between a time of knowing and a time of not knowing and what the cause was that separated the two.
By virtue of the fact that elsewhere in Scripture, we learn that God knows all things. If we were to accept your exegesis, this would mean that there’s a serious contradiction in Scripture. And, we know that this is not the case. Therefore, we reject your exegesis.
So I can’t use this passage to show an inconsistency in Scripture, becuase doing so would show an inconsistency in Scripture, and you declare by fiat that there is no inconsistency in Scripture. Imagine if we can do that for anything: “You can’t show that our new medicine can cause people to grow a third eyeball, because that would mean there is a problem with our medicine, and we know that there are no problems with our medicine.”
How about “until now, I did not know.” That would prove your assertion. However, in the absence of any such thing, your assertion that “now I know, since…” actually means “before now, I did not know” simply doesn’t hold up to scrutiny.
Both phrases mean EXACTLY the same thing. Each imparts that there is a change in knowing and it’s occurring now. “Now I know” emphasizes that the speaker knows from now to the future. “Until now, I did not know” emphasizes that the speaker did not know between the past and now.
