prophet, priest and king

do you know these roles? they're actually something that my particular denomination holds to as a deep part of our identity and heritage.
however, when it comes to truly understanding these toles, i'm not sure we really get it. it's challenging to understand things about God which require faith and trust in something mysterious and not quickly (linearly) plotted on a flow chart.
And i can't blame some of the hesitation and skepticism, really. We've experienced a few folks in this century who have sensationalized the prophet role, especially, in such a way that I am skeptical and hesitant.

But I'm curious, and I want to hear from God.
So I keep pressing in to scripture and pressing in to what I know.
I've heard from God in a variety of ways, lately. Consistently thru scripture, but also in a number of other ways. The unity of teaching on hearing God's voice points me to test these "words" in a variety of ways.
1-all words must be about the glorification of God. (Ask, does this "prophecy" glorify God?)
2-all words must agree with God's word
3-test it by asking others to witness to it
4-watch for the fruit (although this one may take awhile)

so i continue on the journey...praying, listening, hearing, and testing the word...
It IS mysterious. But it's also very exciting.
