you said, "Why would they desire to look into something which has the sole purpose of demonstrating and showing how gods will was both fulfilled and will be fulfilled? You're saying they already know this, but the bible is showing that they know no more than we do, and the gospel was revealed to man, not Angels- as the word means they long to have, or covet, WHAT THEY DO NOT POSESS."
the bible doesn't say that the angels don't know the gospel. Yes, the gospel of Christ was revealed to men but that doesn't preclude the angels hearing it too, not at all. That's why they rejoice when someone accepts the gospel of salvation...(perhaps you are of the opinion that the angels are a bunch of dumb, dumbs cheering for they know not what?)
Why would the angels desire to look into something (the gospel) if they already knew? is what you asked me (i think)
First of all I want to be clear that I agree with you that the angels don't know anymore about the gospel than the apostles. That doesn't mean they know less either.
why do WE desire to look into something (the bible) when we already "know"?...because we tend to focus on something we appreciate, love and have a passion for. (like a deer pants after water)To that extent man can covet the word of God too but it doesn't mean at all that we don't know what it says.
