The Bible is divided into two main parts: the Old Testament and the New Testament. Understanding how they differ - and how they connect - is essential for anyone wanting to understand Scripture.
A Quick Overview
Think of the Bible as a two-part story. The Old Testament sets the stage by introducing God, creation, humanity's problem (sin), and God's promise to fix it. The New Testament shows how that promise was fulfilled through Jesus Christ.

The Old Testament Explained
The Old Testament (also called the Hebrew Bible or Tanakh in Jewish tradition) contains 39 books written over roughly 1,000 years. It's organized into several sections:
The Pentateuch (Torah) - 5 Books
Genesis, Exodus, Leviticus, Numbers, and Deuteronomy. These books cover creation, the patriarchs (Abraham, Isaac, Jacob), the Exodus from Egypt, and God's law given to Moses.
Historical Books - 12 Books
From Joshua through Esther. These chronicle Israel's history from entering the Promised Land through the Babylonian exile and return.
Wisdom Literature - 5 Books
Job, Psalms, Proverbs, Ecclesiastes, and Song of Solomon. Poetry, songs, and practical wisdom for daily life.
Prophetic Books - 17 Books
Isaiah through Malachi. Messages from God's prophets calling Israel to repentance and pointing forward to the coming Messiah.
The New Testament Explained
The New Testament contains 27 books written over approximately 50-60 years, all in the first century AD. It's organized as follows:
The Gospels - 4 Books
Matthew, Mark, Luke, and John. Four accounts of Jesus's life, teachings, death, and resurrection, each with a unique perspective.
Acts of the Apostles - 1 Book
The history of the early church from Jesus's ascension through Paul's imprisonment in Rome. Written by Luke as a sequel to his Gospel.
Epistles (Letters) - 21 Books
Letters from apostles (primarily Paul, but also Peter, John, James, and Jude) to early churches and individuals. They contain theology, practical instruction, and encouragement.
Revelation - 1 Book
Apocalyptic prophecy about the end times, Christ's ultimate victory, and the new heaven and earth.
Key Differences
Different Covenants
The word "testament" means covenant or agreement. The Old Testament describes God's covenant with Israel through Moses - a covenant based on law. The New Testament introduces a new covenant through Jesus - one based on grace and faith.
Different Time Periods
The Old Testament spans from creation (traditionally dated around 4000 BC) to about 400 BC. The New Testament covers roughly 4 BC (Jesus's birth) to about 95 AD (the writing of Revelation).
Different Main Characters
The Old Testament focuses on figures like Adam, Noah, Abraham, Moses, David, and the prophets. The New Testament centers on Jesus Christ, His apostles, and the early church.
Different Emphasis
The Old Testament emphasizes God's law, Israel's history, and prophecies of the coming Messiah. The New Testament emphasizes Jesus as that Messiah, salvation by grace, and the growth of the church.
How They Connect
Despite their differences, the Old and New Testaments form one unified story. Here's how they connect:
Prophecy and Fulfillment
The Old Testament contains over 300 prophecies about the Messiah that the New Testament shows Jesus fulfilling - from His birthplace (Micah 5:2) to His manner of death (Psalm 22).
Promise and Completion
God's promise to Abraham that "all nations will be blessed through you" (Genesis 12:3) finds its completion in Jesus, through whom salvation is offered to all people.
Shadow and Reality
Many Old Testament practices - sacrifices, the temple, the priesthood - were "shadows" pointing to realities fulfilled in Christ. Jesus is the ultimate sacrifice, the true temple, and the eternal high priest.
Jesus's Own Teaching
Jesus frequently quoted and referenced the Old Testament, affirming its authority. He said He came not to abolish the Law but to fulfill it (Matthew 5:17).
Should I Read Both?
Absolutely. While beginners often start with the New Testament (particularly the Gospels), the Old Testament provides essential context. You'll understand Jesus's teachings more deeply when you know the stories, prophecies, and laws He referenced.
Think of it this way: you could watch the final act of a play and understand the ending, but the story makes more sense when you've seen the earlier acts too.
