Every prophecy of the OT was fulfilled when Christ lived, died, buried, raised, ascended and established his church. Matthew 24 was fulfilled at the fall of Jerusalem. Revelation was about the fall of Rome (Domition in particular) with the exception of the last couple of chapters which are about the resurrection and judgment.
every prophecy of the old testament was fulfilled is a very false and dangerous statement
Isa 9:6For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called
WONDERFUL, Counsellor, The mighty God, The everlasting Father, The Prince of Peace.
this old testament prophecy has not been fulfilled yet. and in Is 53 it says that he will divid the spoil from the strong this also as many others has not been fulfilled yet
