The superior authority of Christ meant that while the authors of the NT embraced the OT as 'God-breathed' and thus would never feel free to reject any portion of it, they were equally convinced that the ultimate God-intended meaning of any given passage, and of the OT as a whole, was only found when seen in relation to Christ.
For example, for one or more of the Gospel authors, Jesus's birth fulfills Israel's longing for a messiah, his exodus out of Egypt fulfills Israel's exodus out of Egypt, his temptations in the desert fulfills Israel's trials in the desert, his twelve disciples fulfill the mission of the twelve tribes of Israel, his five sets of teachings in Matthew fulfill Moses’s Pentateuch, his sufferings fulfill the call of Israel to be a suffering servant, and his resurrection is the fulfillment of Israel's calling and longing for restoration.
