How would anybody know if he has encountered a "New Testament" Prophet or not> A New Testament Prophet is not the same as a "Old Testament" Prophet.
If you notice by your OLD TESTAMENT READING, When The Old testament Prophet came on the scene. Look out, They had a message of coming Doom! from the hand of GOD!
This is how He applied it, "I will bless with this If you do this", But if you don't do what i tell you to do, i am going to do this to you" So in the day I do this to you, you are going to Know I am GOD! I am not going to kill all of you, but I am going to save SOME of you in Captivity, to be a witness.

Those Prophets had "If's and but's and when you do" in their messages! They were Prophets of impending DOOM! Most people did not want to see a "Prophet" of GOD come on the scene! Dooms day! "Did not i tell you" if you didn't do what i told you"!
They tell Him to go away, we want a "Prophet that tells us good things" We want the "Prosperity Prophet"! and don't call Jesus either, for He also has a lot of "If's" and buts in His Prophecies too
So How can you tell or do anyone know what a New Testament Prophet is? Is He a Prosperity or a Prophet of Impending Doom? Or is He a "fortuneteller"or clairvoyance.. Because the Letter to the Hebrews, said this;
(Hebrews)BSB
