Not all Scripture is propositional, some of it is asking questions, some of it's rhetorical, but where Scripture is stating something, asserting something, making a truth claim, uttering a proposition that is claiming to be true, it is the truth.

It's better to emphasize biblical theology, partly because there are fine Study Bibles already available that lean into systematic theology, and partly because biblical theology is particularly strong at helping readers see how the Bible hangs together in its own categories: that is, God in his infinite wisdom chose to give us his Word in the 66 canonical books, with all of their variations in theme, emphasis, vocabulary, literary form, and distinctive contributions across time.

I can say that it's 10 miles from my home to Trinity, when in fact that's not quite right, it's off by about 10%, but nobody would say that I'm telling a lie or making a mistake when I rounded off because that's the way we speak and rounded off terms regularly.
