The character of the one who inspired it? As represented in the same work, the bible? The jealous, proud, petty, angry, racist, blood lusting, infanticidal, misogynistic, homophobic, God of the bible?
It's a good line to use. If someone is reading the Bible and is coming up with a picture of God in the way you described above, their viewpoint is distorted in some way. A natural reading of the Bible doesn't lead to those conclusions.
I agree with what you posted in your original meme, that arguing for the Bible's truth on the basis of fulfilled prophesy is not a very persuasive presentation, since other religious texts make that claim too (and even when the prophecies fulfilled can be verified, there are other possible explanations besides divine intervention to explain that phenomenon).
Honestly I feel like God is none of those characteristics, all in context of the situation and such would show a real light. He is a Just merciful and powerful God. And plus with the whole jealous thing, I’m pretty sure that was more of a way to show how one should share praise to God with another false god. Same way we aren’t supposed or put anything or anyone before Him, we should hold anything or anyone or a pedestal beside/ next to him.
