What I hear you asking is that those who proclaim themselves to be "prophets" and/or "watchmen", (watchmen not being a NT office or gift as far as I can tell) to be held to the same standards that they "exact" on others.
They expect to be received as who they say they are without any evidence other than that they say so.
Since they are not here in person it is impossible to experience any anointing they may or may not have.
Everyone has been in a meeting and/or service in which the minister was anointed and we have all been in meetings and/or services when the minister was not anointed. When there is no anointing it is time to go home.
The "prophecies" I have seen on this forum are so general that they will "hit" someone.
If a person is going to proclaim that they are called of God to be a prophet or whatever and that person is going to stand up and warn against anyone, what is it that we should receive and believe what they say.
There are no anointing, credentials, or any other way to tell if what they say is true as most of it is a matter of opinion on a forum like this.
The so called prophets can be judged by what they "prophesy".
If the prophesy is just general it is not God, even though some say it helped. The same thing could have been posted without proclaiming it "thus saith the Lord".
A prophesy that does not come to pass or prevent a major disaster when it is given is not from God.
Excellent post CA.
