I would agree for the most part except perhaps the use of the word prophecy. True that the parables held hidden meaning dna teachings but this isn't always how prophecy works. Wise and guiding teaching hidden in plain sight most of the time is exactly that a hidden lesson that requires one to look deeper than what the human mind or eyes see in it however prophecy itself isn't this it normally points to somethingWhatever works for you.
I have been paying attention. Without parables Christ spoke not deliberately . . purposely to teach us how to walk by faith (the unseen). Hiding the understanding as prophecy the gospel from those who walk after wondering marveling walking by sight as a form of amusement . The foundation of Paganism .out of sight out of mind . . First it was the tongue of God is not prophecy so that you could keep the lying wonder .I made a noise and fell backward. "Nothing proves nothing. And now parables are not prophecy making them nothing that proves nothing. .
Why did Christ hide the meaning in prophecy called parables if it was not to teach us how to walk by faith . His faith as a labor of love working in us?
Parables in how Jesus used them are kind of like how God teaches me using analogies it's kind of like a story telling with inportant lessons and deeper learning in it. True enough this also can be a form of propehcy but Jesus's intent was to guide those who would understand the meaning of it into a deeper understanding of God and who he is I don't think it was intent to prophecy
