Short answer: No. Writing in your own Bible, underlining verses and highlighting passages is not a sin. The Bible says nothing against it, and the warnings about adding to God's word are about changing what Scripture says, not about taking notes in the margin. The one place to hold back is a Bible that belongs to someone else, such as a borrowed or library copy.

Many believers grew up with the feeling that a Bible is too holy to touch with a pen. Others take notes in every margin and wonder if they should feel guilty. Both groups ask me the same thing, and the question behind it is a good one: how do I treat God's word with proper respect?
I will cover why people think it might be a sin, what Revelation 22 and Proverbs 30 actually warn against, what Scripture says about writing and meditating on it, when you should not mark a Bible, and some simple habits that make notes worth keeping.
Is It A Sin To Write In Or Highlight Your Bible?
The Bible gives no command about underlining, highlighting or writing in margins. There is no verse that forbids it, and no teaching in Scripture that a physical copy becomes defiled if a believer marks it. The paper is not what is sacred. The message is.
People who object to marking a Bible usually act out of real respect. They love the book and fear treating it carelessly. I honour that. But respect is shown by obeying and treasuring what the Bible says, and a highlighter does not change a single word of it. Our goal in reading is to understand it and remember it, and marking helps many people do that.
I have hidden your word in my heart that I might not sin against you.
Psalm 119:11 (NIV)
If underlining a verse helps you hide it in your heart, then it serves what the psalmist wants. The same goes for writing a short prayer or question beside a passage.
What Do Revelation 22:18 And Proverbs 30:6 Warn Against?
These two passages are the ones usually brought out against marking a Bible, so they deserve a careful look.
If anyone adds anything to them, God will add to that person the plagues described in this scroll.
Revelation 22:18 (NIV)
The warning in Revelation 22:18-19 is addressed to those who add to or take away from the words of the prophecy. It is about the message: teaching something God did not say, or removing what he did say. Proverbs 30:5-6 works the same way.
Do not add to his words, or he will rebuke you and prove you a liar.
Proverbs 30:6 (NIV)
Both are about falsifying God's word. Writing a note in the margin does not alter the text. You are not adding to the Bible, you are adding to your copy of it, and the words of Scripture stay exactly as they were. If I mark Romans 8 in green, the next person who opens a fresh Bible finds the same chapter. A note that records what a passage taught you is not a rival revelation. It is a study aid.
If you are curious about handling Scripture with care in other ways, I have written about throwing away a Bible and not reading a Bible. In my view, a neglected Bible on a shelf is a bigger problem than a well-marked one that is read every day.
Does The Bible Encourage Writing And Meditating On God's Word?
Quite the opposite. Scripture is full of instructions to engage with the word in active ways. Israel was told to fix the commands on their hearts and to write them down.
Write them on the doorframes of your houses and on your gates.
Deuteronomy 6:9 (NIV)
God told Joshua to meditate on the law day and night.
Keep this Book of the Law always on your lips; meditate on it day and night, so that you may be careful to do everything written in it.
Joshua 1:8 (NIV)
Meditation is not passive. It involves slowing down, asking questions, noticing patterns and remembering. Many people do that best with a pen in hand. Marking up a passage, drawing a line between connected thoughts, or recording what struck you is simply one way of meditating on the text. God cares far more that we read, understand and obey than that our pages stay clean.
Why Do Some Christians Feel Marking A Bible Is Sinful?
Often it comes from how we were taught. If you grew up thinking God was waiting to punish every slip, you may feel guilty about things the Bible never forbids. That mindset treats faith as a list of rules to keep God happy, rather than a relationship with a Father who loves you.
God does not hold back, waiting to punish you for annotating a Bible. He wants you to understand what he has said. I would encourage you to ask whether the rule you feel was taught from Scripture or just passed down. If it is not in the Bible, you are free. If you struggle to read the Bible at all, start with how to read the Bible and where to start reading the Bible.
When Should You Not Write In A Bible?
There are a few cases where I would hold back, and they are about respect for people, not for paper.
- A Bible that belongs to someone else. If you borrowed it from a friend, a church or a library, do not mark it without permission. Not everyone likes notes in their Bible, and marking another person's property without consent is simply unkind.
- A family heirloom. If a Bible carries the handwriting of a parent or grandparent, you may want to leave it as it is and use a separate copy for your own study.
- A pew Bible or shared Bible. These are meant to serve many readers.
A Bible that you own is yours to use. What you underline there is between you and God. It is not a public statement.
How Can You Mark Your Bible Well?
A few plain habits keep notes useful. Use a pen or highlighter that will not bleed through thin pages, or try a pencil if you want to revise. Keep a short key, perhaps one colour for promises and another for commands. Write the date or situation next to a note so that you remember what the verse meant to you then. Do not mark so much that nothing stands out.
If you want a Bible built for study, with room for margin notes, a study Bible is worth considering, and I review one in my NIV Study Bible review. Whatever you pick, the point of the marks is to get you back into the text. If you find yourself decorating pages without reading them, put the highlighter down and read.

Frequently Asked Questions
Is it a sin to highlight in the Bible?
No. Nothing in Scripture forbids highlighting, and it can help you remember what you read. Highlighting does not change the words, so it does not break the warnings against adding to God's word.
Is it a sin to write in my Bible?
No, not in your own Bible. Notes in the margin are a study aid, not an addition to Scripture. The one exception is a Bible that belongs to someone else, where you should get permission first.
Can I use a highlighter in my Bible?
Yes. Choose a highlighter or pen that will not bleed through thin pages, or use a pencil if you want to change notes later. Keep your marks simple so that key passages still stand out.
Are you allowed to highlight things in the Bible?
You are free to mark your own copy. The only limits are courtesy: do not write in a borrowed, library or shared Bible without consent. Read how to read the Bible for ideas on using notes well.
