May the Prophets’ Voice be heard

“And whether they heed or resist–for they are a rebellious house–they shall know that a prophet has been among them.”

I was struck by this line from the first reading of today’s Liturgy. Ezekiel is forewarned that his words may or may not be heard, they may or may not be heeded.

What prophetic voices do I need to hear and heed? Who in today’s world is speaking Divine words to the obstinate of heart?
