“For if you believed Moses, you would believe me; for he wrote of me. But if you do not believe his writings, how will you believe my words?” (John 5:46-47, ESV).
The Old and New Testaments of the Judeo-Christian Scriptures form the complete revelation of God’s direct communication to the men He created. This truth is under-emphasized in our day. Some strains of theology today suggest — if they don’t teach outright — that the New Testament has replaced the Old Testament, even that a Christian doesn’t need to read the Old Testament. Such teaching is wrong.
The New Testament is truly the final recorded Word from God, and it contains the essential teaching about Jesus’ life, death and resurrection, but it doesn’t make the Old Testament obsolete. Jesus Himself observed in the passage quoted above that “[Moses] wrote of Me.” Therefore to appreciate the singular intent of God in this world, it is important to understand the Old Testament as well as the New.
Someone who is a true basketball fan doesn’t merely tune into a game for the last 2 minutes of the game; he arranges his schedule to watch the whole game. A lot happened in the game before the last two minutes. Similarly, a lot happened in our world to bring us to Jesus. We can’t fully understand the New Testament until we have a grasp of the Old.
For example, why did Matthew begin his Gospel with the genealogy of Jesus? It was because of the promise given to King David that Messiah would come from his descendants. Without this knowledge, the first few verses of Matthew (and a portion of Luke’s Gospel as well) would be merely a long list of often-unpronounceable names that have no relevance to life today.
The Old Testament records the ways God has tried to communicate His Truth to men from the beginning. Sin had entered this world and God was/is intent on redeeming men despite it. Beginning in Genesis 3, He promised to send a person who would crush the serpent who had tempted men to sin. That person would become known in Jewish writings as “Messiah” and would be “a prophet like Moses” (Deut 18:15).
The list of hints, prophecies and pictures of Messiah are contained in almost every book of the Old Testament. Messiah Jesus didn’t just appear on the scene one day; He was the fulfillment of a long, remarkable plan of God to redeem men.
This is why our church has celebrated Passover for the past several years. This Jewish feast was intended by God (through Moses) to help His people to recognize Messiah when He came. Sadly it just became a ritual handed down from generation to generation. Happily, though, some of us have seen the fulfillment of the Old Testament in Jesus, and it has enriched us beyond measure.
