What is the Old Testament and Why Does It Matter Today?
What is the Old Testament and how is it structured?
The Old Testament comprises the 39 books of the Hebrew canon, written primarily in Hebrew to document God’s history with the people of Israel.
In 15+ years of teaching this text, I have observed that many readers view the Old Testament as a collection of disjointed stories, yet it is a cohesive historical record. It serves as the foundation for everything that follows in the New Testament. Most people struggle with its vast scope, but when you see the unifying theme of covenant, the narrative begins to clarify.
How are the 39 books typically categorized?
The Old Testament is divided into four main sections: the Law, History, Poetry and Wisdom, and the Major and Minor prophetic writings.
These divisions help organize the narrative flow from creation to the return from exile. Scholars often point to these categories to distinguish between instruction, national chronicle, and divine messages. Understanding these literary genres is key to studying the Bible accurately.
- The Pentateuch: Genesis through Deuteronomy (The Law)
- Historical Books: Joshua through Esther
- Poetic/Wisdom Literature: Job through Song of Solomon
- Prophetic Books: Isaiah through Malachi
What languages was the Old Testament originally written in?
The text was written almost entirely in Hebrew, with small portions of Daniel and Ezra recorded in Aramaic during the exilic period.
The linguistic precision of the Hebrew text is a testament to the care taken by scribes over centuries. While modern translations vary, the original manuscripts provide the scholarly bedrock for our current theological understanding of Scripture.
Why is the Old Testament relevant for Christians in 2026?
The Old Testament provides the essential historical and prophetic context required to fully comprehend the life and mission of Jesus Christ.
One of the most common misreadings is that the Old Testament is a separate, obsolete book. In reality, Jesus and the apostles quoted these texts constantly to prove his identity. It is not a secondary work but the prologue to the Gospels.
How does the Old Testament point to Jesus Christ?
The Old Testament uses typology, prophecy, and covenant promises to establish a clear expectation of the coming Messiah for the nations.
From the sacrificial system to the prophecies of Isaiah, the entire structure anticipates a future Savior. Scholars note that over 300 specific references in the Old Testament are fulfilled in the life of Jesus. Ignoring these links leaves a massive gap in one’s walk of faith.
| Theme | Old Testament Basis | New Testament Fulfillment |
|---|---|---|
| Sacrifice | Levitical Law | Christ the Lamb |
| Deliverance | The Exodus | Spiritual Salvation |
| Covenant | Abrahamic Promise | New Covenant in Blood |
What does the Old Testament teach about the character of God?
The Old Testament reveals God as holy, just, faithful, and patient, establishing the moral framework that guides all biblical theology.
Many people find the portraits of God in these books difficult, but they are consistently presented with a focus on his covenant loyalty. He is not merely a judge, but a pursuing Father. Studying these accounts teaches us about divine patience that spans generations.

How was the Old Testament canon formed?
The 39‑book Protestant Old Testament emerged from a gradual process of communal recognition, scholarly debate, and council decisions spanning centuries.
Early Jewish communities grouped the Torah, Prophets, and Writings as authoritative, but the exact boundaries were discussed in rabbinic academies such as the Council of Jamnia (c. 90 CE). Christian writers later affirmed the Hebrew canon while the Septuagint included additional books, leading to the Protestant Reformation’s return to the Hebrew 39‑book list.
In my experience, those who engage with the Old Testament find their faith significantly strengthened. It is a rich, challenging, and beautiful narrative that introduces us to the God who keeps his promises. — Pastor Thomas Whitfield, M.Div.
