What Most Christians Get Wrong About the Old Testament
Be honest, when was the last time you opened the Old Testament and didn't land on Psalms or Proverbs?
If you're like most Christians, the Old Testament feels like that long prologue you skip to get to the good stuff. You know it's there. You know it's important. But between the genealogies, the laws about mildew, and the wars you can't pronounce, it's easy to think, "I'll just stick with the New Testament."
Here's the problem with that: if you skip the Old Testament, huge parts of the New Testament stop making sense. The cross becomes an event without a context. Grace becomes a word without a weight. And Jesus becomes a character who showed up out of nowhere instead of the one the entire Bible had been pointing to all along.
So let's talk about what most Christians get wrong, and why the Old Testament matters more than you think.
"It's Just a Bunch of Rules and Wars"
This is probably the most common reason people avoid the Old Testament. And on the surface, it makes sense. You open to Leviticus and it's laws about skin diseases. You flip to Joshua and it's city after city being conquered. It can feel dry, violent, and irrelevant.
But here's what you're missing when you see it that way: the Old Testament isn't a rulebook. It's a story.
It's the story of God creating a people, pursuing them relentlessly, and watching them walk away over and over again. The laws weren't arbitrary hoops to jump through, they were God showing Israel what it looked like to be set apart in a world full of idolatry. The wars weren't random violence, they were part of God establishing a nation through which He would eventually bring the Messiah.
Even the genealogies serve a purpose. Matthew 1 traces Jesus' lineage all the way back through the Old Testament to show that He was the fulfillment of promises made centuries earlier. If you skip the Old Testament, you lose the thread that ties it all together.
As Paul wrote in 2 Timothy 3:16, "All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness." All Scripture, not just the parts that are easy to read.
"That's Old Covenant, It Doesn't Apply to Me"
There's a half-truth floating around in a lot of churches that goes something like this: "We're under the new covenant now, so the Old Testament doesn't really apply."
And yes, the new covenant does change things. Hebrews 8:13 says, "In speaking of a new covenant, he makes the first one obsolete." So there's a real theological shift that happens through Christ.
But here's the part people miss. Jesus Himself said in Matthew 5:17, "Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them."
That word fulfill is doing a lot of work. It means that everything the Old Testament pointed to, the sacrificial system, the priesthood, the promises to Abraham, the prophecies of Isaiah, all of it finds its completion in Jesus. He didn't cancel the Old Testament. He completed it.
So when you skip it, you're not just skipping ancient history. You're skipping the setup that gives the gospel its meaning. You can't fully appreciate what Jesus did if you don't understand what came before Him.
Think of it this way: imagine watching only the last thirty minutes of a movie. You'd see the resolution, but you wouldn't feel it. You wouldn't understand the stakes, the tension, or why it mattered. That's what reading only the New Testament is like.
"The God of the Old Testament Is Angry, the God of the New Testament Is Loving"
This might be the most damaging misconception on this list. A lot of people, Christians included, have this picture of a two-faced God. Wrathful and terrifying in the Old Testament. Gentle and forgiving in the New.
But that's not what Scripture teaches. Not even close.
Look at Exodus 34:6-7. God is revealing His own character to Moses, and here's what He says: "The LORD, the LORD, a God merciful and gracious, slow to anger, and abounding in steadfast love and faithfulness, keeping steadfast love for thousands, forgiving iniquity and transgression and sin."
That's the Old Testament. That's God describing Himself, merciful, gracious, slow to anger, overflowing with love.
Or look at Psalm 103:8-10: "The LORD is merciful and gracious, slow to anger and abounding in steadfast love. He will not always chide, nor will he keep his anger forever. He does not deal with us according to our sins, nor repay us according to our iniquities."
Or the entire book of Hosea, where God compares His love for unfaithful Israel to a husband who keeps pursuing a wife who has left him. That's not a picture of an angry God. That's a picture of a heartbroken one.
And if we're being honest, the New Testament has its share of judgment too. Read Revelation. Read Acts 5, where Ananias and Sapphira are struck dead for lying to the Holy Spirit. Read the words of Jesus in Matthew 23, where He calls the Pharisees "whitewashed tombs" and "a brood of vipers."
God doesn't change between testaments. Malachi 3:6 says, "For I the LORD do not change." His character is consistent from Genesis to Revelation, holy, just, merciful, and loving. The Old Testament and the New Testament reveal the same God.
"I Just Read Psalms and Proverbs"
There's nothing wrong with Psalms and Proverbs. They're beautiful, comforting, and full of wisdom. But if that's all you read from the Old Testament, you're only getting part of the picture.
The Psalms give you worship and lament. Proverbs gives you wisdom for daily life. But what about Job, where a righteous man loses everything and wrestles with God for answers? What about Ecclesiastes, where Solomon, the wisest man who ever lived, looks at life and says, "Vanity of vanities! All is vanity" (Ecclesiastes 1:2)?
What about the prophets? Isaiah, who saw the holiness of God and cried out, "Woe is me! For I am lost" (Isaiah 6:5). Jeremiah, who wept over a nation that wouldn't listen. Habakkuk, who asked God hard questions and was told to trust even when it didn't make sense.
These books aren't filler. They're where you find the Bible at its most raw, most honest, and most human. They show people wrestling with suffering, injustice, doubt, and the silence of God, and they show God meeting them in all of it.
If you only read the comfortable parts, you'll build a faith that only works when life is comfortable. But life isn't always comfortable. And the Old Testament gives you the language to bring your real life, the messy, painful, confusing parts, before God without pretending everything is fine.
Why the Old Testament Makes Jesus Make More Sense
Here's where it all comes together.
Without Genesis 3, you don't understand why humanity needs saving in the first place. Without the fall, Romans 5:12, "sin came into the world through one man", is just a theological statement floating in a vacuum.
Without the sacrificial system laid out in Leviticus, you can't grasp the weight of Hebrews 9:22: "Without the shedding of blood there is no forgiveness of sins." The cross isn't just an act of love. It's the fulfillment of a pattern God established thousands of years earlier.
Without Isaiah 53, "He was pierced for our transgressions; he was crushed for our iniquities", you lose one of the most breathtaking prophecies about Jesus, written roughly 700 years before He was born.
Without the covenant God made with Abraham in Genesis 12, the promise that through his offspring all nations would be blessed, you miss the storyline that runs through the entire Bible and lands in Galatians 3:16: "Now the promises were made to Abraham and to his offspring... who is Christ."
Jesus didn't appear out of nowhere. He was promised, foreshadowed, and prepared for across the entire Old Testament. Luke 24:27 says it plainly: "And beginning with Moses and all the Prophets, he interpreted to them in all the Scriptures the things concerning himself."
If Jesus thought the Old Testament was about Him, maybe we should pay more attention to it.
Where to Start
You don't need a seminary degree to read the Old Testament well. You just need to stop skipping it.
If you've never spent much time there, here are a few places to start. Genesis gives you the foundation, creation, the fall, the flood, the patriarchs, and God's covenant with Abraham. Exodus shows you God rescuing His people and revealing His character. The Psalms give you the language of prayer and worship. Isaiah gives you some of the most powerful prophecies about Jesus in the entire Bible.
Start anywhere. Read slowly. Ask questions. Pay attention to what God is revealing about Himself, His holiness, His patience, His faithfulness, His love.
The Bible is one story, from Genesis to Revelation. And right now, you might be missing half of it.
Don't settle for half a Bible. The whole thing points to Jesus, and the more of it you read, the more clearly you'll see Him.
