John 1:45
Philip found Nathanael and said to him, "We have found Him of whom Moses in the law, and also the prophets, wrote — Jesus of Nazareth, the son of Joseph!"
NKJV
The earliest disciples were thrilled to find fulfillment of prophecy, in this case, the fulfillment of prophecy regarding the promised Messiah. (See also the fuller context of John 1:22-50). The Gospel of Matthew constantly refers to the prophecies that were being fulfilled with every act of Jesus. (And Matthew records how Jesus held prophecies in mind that He was conscientious to fulfill as each opportunity arose). We, likewise, should be eager to find the fulfillments to each of the prophecies of the Bible and, as those earliest disciples, find great reward in doing so. It's like finding hidden treasure!
