In his book The Riches of Divine Wisdom, David Gooding notes that the writers of the New Testament had a distinct advantage over the Old Testament prophets in that they now looked back on the prophecies and histories of the Old Testament from the vantage point of having witnessed their fulfillment in Christ. Gooding writes:
“In that light it was inevitable that they should perceive that the intended meaning and scope of God’s Old Testament prophecies were often far greater than many people realized at that time.”
Makes sense. The more light you have, the more you can see.
