“New revelation cannot mean contradictory revelation. Later revelation on a subject does not make the earlier revelation mean something different.”48 “If this were so,” according to Ryrie, “God would have to be conceived of as deceiving the Old Testament prophets when He revealed to them a nationalistic kingdom, since He would have known all the time that He would completely reverse the concept in later revelation.” 49
What if the NT doesn’t change the meaning, but rather clarifies the original meaning? Many OT texts are difficult to interpret. The NT authors are inspired interpreters of OT texts. Doesn’t it make sense to trust their view over ours?
Furthermore, we see that the coming of Christ significantly surprised the Jews. He did not meet their expectations. Perhaps their understanding of certain OT texts was wrong all along. Jesus and the apostles clarify what God originally meant in OT texts.
