Who today claims to be God's prophets? If the governing body of jehovah's witnesses deny this, or state before onlookers that it would be presumptuous to believe they are the only prophets or only spokesperson that god is using - such as Geoffrey Jackson's statement at the ARC (when taken in the context of the question) - then who does the scriptural statement default to?
Christian Congregation of Jehovah's Witnesses:
For the Sovereign Lord Jehovah will not do a thing unless he has revealed his confidential matter to his servants the prophets.
The Church of Jesus Christ of Latter Day Saints:
Surely the Lord GOD will do nothing, but he revealeth his secret unto his servants the prophets.
Who are the prophets of Amos 3:7?
