The Biblical Importance of the Old Testament

  1. Why is the Old Testament so important if we now have the New Testament?
  • In a similar way, the New Testament is the final chapter of the Old Testament. It is the fulfillment of the Old Testament. The Old and New Testaments work together to give us the whole picture of who God is, who we are and what God does with our rebellion. The Old Testament forms a backdrop against which we can understand the New Testament. The New Testament is the fulfillment of God’s plans, purposes and promises which he gave in the Old Testament. 

As such then you can say that both the Old and New Testaments are about Jesus (We can be sure of this because there are many scriptures in the old testament that write about the coming Messiah) – In summary we can say that the Old Testament points to Jesus, and the New Testament describes the life, death and resurrection of Jesus, and reflects on the impact this Christ has in the world and the fulfillment of Old Testament prophecy.

  1. Does the New Testament Replace the Old Testament?
  • Many people, primarily followers of Christ present a claim that ruffles a lot of feathers in the church on whether Christians should still follow what God spoke in the old testament. These claims are usually presented like this, “That was in the old testament and doesn’t apply to me” or “The old Testament is outdated, therefore it’s not necessary to understand.” So, does the New Testament replace the Old? 

New Testament scriptures complete—not contradict or replace —Old Testament scriptures. As such, the Old Testament must be interpreted in light of the New Testament. We see this fulfillment in Jesus Christ, who says himself in (Matthew 5:17-19), that He came not to abolish the law of Moses in the old testament but to fulfill (complete it) and because of Christ, we are not under the law any longer but under grace. 

In summary, the bible says that God himself does not change (James1:17). When the old testament was written and when God gave Moses the ten commandments, God did not have in mind to wipe them out in the New Testament because God’s law itself is perfect and holy (Romans 7:12, 14). Rather, there are many laws in the Bible. Some more specific to the old testament covenant, while others predate and extend through both the Old Covenant and the New Covenant. Many laws that were in the Old Testament are still essential today and God still intends for us to obey them, they all are intended to give us a deeper understanding of what God expects and how He wants us to live. Overall, we as followers of Jesus should obey the word of God in fullness because obeying God’s commands is a true sign that we love Him, (John 14:15)

  1. The purpose of the Old Testament and eight biblical reasons on why it is important for Christians to know.
  • The first reason the Old Covenant or Testament is important, is because it is the written record of the origin, terms, and history of the solemn agreement which existed between the Israelite nation and Jehovah and is the inspired word of God. The second reason for the purpose of the Old Testament was its foreshadowing of the things to come in Christ Jesus, Christ’s sacrifice was for all and was the ultimate sacrifice for sin to bring the world back to redemption to God, (Hebrews 10:1-2)

Eight Biblical Reasons

1. The OT was Jesus’s only Scripture and makes up three-fourths (75.55 percent) of our Bible. (Matt. 5:17; Luke 24:44; Acts 24:14; 2 Tim. 3:15)

2. The OT substantially influences our understanding of key biblical teachings.

(Eph. 5:19; Col. 3:16)

3. We meet the same God in both Testaments. We see God’s wrath and mercy displayed in both the old and new testament. 

(Heb. 1:1–2, Exodus 34:6, (Heb. 10:26–27)

4. The OT announces the very ‘good news/gospel’ we enjoy.

(Gal. 3:8, Rom. 1:1–3, 16, Isa. 61:1; 40:9–11; 52:7–10; Luke 4:16–21).

5. Both the old and new covenants call for love, and we can learn much about love from the OT.

(Deut. 6:5; 10:19, Matt. 22:37–40)

6. Jesus came not to destroy the Law and the Prophets but to fulfill them.

(Matt. 5:17–19)

7. Jesus said that all the OT points to him.

(John 1:45, John 5:39; cf. 5:46–47)

8. The NT authors stressed that God gave the OT for Christians.

(1 Pet. 1:12, Rom. 15:4; cf. 4:23–24)
