Sorry for the delay in responding but I wanted to be at a keyboard when I did, and I've been mostly on my phone the last few days.
I'm sorry my comments came across like how you say in the bolded above. It wasn't my intent at all. What I was really saying is that I consider the "expert" in this situation, more than either of us or even biblical scholars, is Matthew himself. Of course that depends on what you believe about the inerrancy of New Testament scripture. I give it 100% authority, but I don't actually have a good bead on your personal beliefs, and I'm glad you're not offended because no offense was intended. If anything, I think it's very profitable for everyone to genuinely and sincerely seek the truth in these discussions, and to follow their own consciences in what they do with whatever they are able to take away from them. Even if the gospel writers state something as immutable truth, when believers sincerely probe these idioms, exploring them for reasonableness and to understand how they fit into God's plan in our lives and in salvation history, it is very profitable imo (hence the value of this thread

).
SO...having said that, getting back to the point...
In Hebrews 4:12, we read that "God's word is alive, it strikes to the heart. It pierces more surely than a two-edged sword." And in the first chapter of John's gospel, we read that Jesus IS the Word, and again in Revelation 21:5 that (behold!) He makes all things new. So this context is the reason why in my view, for Christians, not just prophecy but
everything in the old testament (and to an extent even what we find in the new testament, and in our own spiritual journeys) has layers of meaning.
We've been talking about Hosea, but we can basically pick out any passage where the OT is talking about a specific instance and also look at it through the lens of how it impacts our world, our Church, and our individual lives. Here's an example, from Isaiah (41:8-10):
8But you, Israel, my servant,
Jacob, whom I have chosen,
offspring of Abraham my friend
9You whom I have taken from the ends of the earth
and summoned from its far-off places,
To whom I have said, You are my servant;
I chose you, I have not rejected you
10Do not fear: I am with you;
do not be anxious: I am your God.
I will strengthen you, I will help you,
I will uphold you with my victorious right hand.
I assume the (human) author of these verses was thinking of the Nation of Israel, and God's promise that he will redeem them, but most Christians will probably interpret this and most of the uses of the term "Israel" in the OT to also apply to Christ's Church. In the same way, prophesy may imo validly be viewed through multiple lenses.
