Scripture has a rather unique definition of fulfillment. While it does follow the usual definition of looking forward to something, it can also refer to looking backward to something as well. The passage of Hosea, fulfilled in Matthew says “[w]hen Israel was a child I loved him, out of Egypt I called my son. The more I called them, the farther they went from me, sacrificing to the Baals, and burning incense to idols” (Hos 11:1-2). However, this passage looks backward, to the time of Exodus and not forward to the time of Jesus, so it seems as if Matthew is incorrect in thinking that the words of Hosea were fulfilled in the Jesus. However, the definition of fulfillment in Scripture also includes fulfilling what has already happened. The Exodus, a moment in the past, awaits fulfillment in a new and more perfect Exodus when Israel is freed from the slavery of sin and death. It is precisely this fulfillment of a past event that Jesus is bringing about. Using this passage from Hosea, it becomes clear how fulfillment in Scripture can refer to both past and future events.
There are many places in which the Gospels of Matthew and Luke address the elements of the Old Testament narrative we discussed in class. The entire first part of Matthew’s Gospel reconciles the question of how it was possible to have both a descendent of David and God Himself as king over the Israelites. By tracing Jesus’ lineage to David (and even further), Matthew lays out the fulfillment of the Davidic covenant and how there might be both a Davidic king and God as king over Israel. Luke’s Gospel also refers to the Davidic covenant when the angel Gabriel tells Mary that Jesus will be given the throne of David and will rule forever.
