Jesus is the fulfillment of all biblical prophecies, and among these there is one particularly important.
In the deuterocanonical legislation, there is a part referring to the prophets, in this section there is a prophecy that the Christian faith attributes to the Lord Jesus: "The LORD your God will raise up for you a prophet like me from among you, from your fellow Israelites. You must listen to him. For this is what you asked of the LORD your God at Horeb on the day of the assembly when you said, ´Let us not hear the voice of the LORD our God nor see this great fire anymore, or we will die.´ The LORD said to me: ´What they say is good. I will raise up for them a prophet like you from among their fellow Israelites, and I will put my words in his mouth. He will tell them everything I command him. I myself will call to account anyone who does not listen to my words that the prophet speaks in my name" Deuteronomy 18:15-19.
The Gospel of John tells us that Jesus is rejected by many, and it is there that our Lord alludes to this prophecy by saying that he is the expected prophet according to deuterocanonical law: "But do not think I will accuse you before the Father. Your accuser is Moses, on whom your hopes are set. If you believed Moses, you would believe me, for he wrote about me. But since you do not believe what he wrote, how are you going to believe what I say?" John 5:45-47.
Jesus perfects the covenant made by Moses in the presence of God on Mount Horeb. Jesus is the personification of God's perfections, he is "the son of man", our Lord is the prophet of the new covenant with God mentioned in the old testament, and this covenant that Jesus brings us is not based on a set of imperatives but on an invitation to God's freedom: "´Love the Lord your God with all your heart and with all your soul and with all your mind.´ This is the first and greatest commandment. And the second is like it: ´Love your neighbor as yourself.´ All the Law and the Prophets hang on these two commandments" Matthew 22:37-40.
