I am studying this great passage & reading several books which highlight it. In Erwin Lutzer's new book "The King is Coming" he says that the discourse will not be fully fulfilled until the tribulation. Perhaps my understanding was wrong on this passage, but I thought the discourse was written for gentile Christians, however according to him the discourse is for the jews. Perhaps I am not understanding something here. Biblical Prophecy has to be the most complex of all the theological fields of study, and this shows by the vast amount of disagreements. It certainly is more complex than debating over evangelism methods, or debating over the doctrine of Limited Atonement.
