Revelation 22:18 — I warn everyone who hears the words of the prophecy of this scroll: If anyone adds anything to them, God will add to that person the plagues described in this scroll.
Explanation of the Verse
This verse is a serious warning. John, writing under the guidance of the Holy Spirit, is telling anyone who reads or hears the words of Revelation not to tamper with them. Specifically, he says that no one should add anything to the message of this prophecy. The consequences are severe: if someone adds to it, God will add to them the plagues that are written in the book.
This is not an empty threat. It’s a strong and loving guardrail to protect the truth of God’s Word. Revelation is the final book of the Bible and the final chapter of God’s revealed message to His people. Adding anything to it—whether extra teachings, visions, or human opinions—twists the truth and misleads others.
God’s Word doesn’t need updates or improvements. What He has revealed is complete and perfect. This verse calls us to humility and respect for Scripture. It’s a reminder to handle God’s Word with care and not to make it say more than it does.
Historical Context
In the first century, false teachers were already spreading lies in the name of God. Some tried to change the message of Jesus to fit their own ideas or desires. Others claimed to have new revelations that went beyond what the apostles had taught.
The book of Revelation was written to churches facing confusion, compromise, and pressure. This closing warning served as a clear line: Do not change the message. God has spoken. Anyone who tampers with His Word, especially something as serious and sacred as prophecy, risks facing God’s judgment.
This warning also reflected how ancient documents were treated. Important legal or royal scrolls often came with statements warning people not to alter them. In that context, this kind of statement would have been taken very seriously.
Theological Implications
This verse reminds us of the authority, sufficiency, and finality of Scripture. The Bible is not a collection of human thoughts—it is God’s revelation to mankind. Revelation, as the last book of the Bible, brings that revelation to its full and final close. Nothing more is needed, and nothing should be added.
It also shows that God watches over His Word carefully. He won’t tolerate distortion or manipulation of His message. Adding to it is not just a mistake—it’s rebellion. This warning guards the truth and protects the Church from error.
The reference to the plagues is especially sobering. Revelation describes powerful and terrifying judgments poured out on the world. To say that someone who adds to Scripture will experience those judgments shows just how serious God is about keeping His Word pure.
Literary Analysis
This verse follows a pattern used in ancient treaties and formal writings, where a blessing was promised for obedience and a curse for disobedience. Revelation 22:14 gave a blessing to those who “wash their robes,” while this verse gives a curse to those who add to the prophecy.
The structure of the sentence is direct: it starts with a personal warning (“I warn everyone”), identifies the subject (“who hears the words of the prophecy”), states the action (“if anyone adds to them”), and gives the consequence (“God will add the plagues”).
The repetition of “add” in both halves of the sentence creates a deliberate, poetic symmetry—showing that the action will bring a mirrored response. It reinforces the justice and fairness of God’s response.

What This Verse Means for Today’s Christian
For believers today, this verse calls us to honor the Bible as the complete, true, and final Word of God. We are not to treat it casually or edit it to fit our personal views or modern preferences. God does not give us the right to add new revelations that override or replace what He has already said.
This doesn’t mean we shouldn’t teach, explain, or apply the Bible—it means we should do so faithfully, without changing its core message. This verse challenges us to approach God’s Word with reverence and to be careful not to twist it, even unintentionally.
It also encourages us to be watchful. False teachings are still common today, and many people claim to speak for God while contradicting His Word. This verse gives us a clear standard: compare every message to the Word, and if someone is adding to what God has said, beware.
How This Verse Relates to a Loving God
God’s love is seen in the way He protects His people from lies. This warning is not harsh—it’s loving. It shows that God cares deeply about the truth, because the truth is what sets us free (John 8:32). Lies, even small ones, can lead people away from salvation, hope, and eternal life.
By warning us not to add to His Word, God is keeping us safe. He is guarding the way to the tree of life, making sure that no one distorts the message of grace. That’s the heart of a Father who wants His children to walk in light, not darkness.
How This Verse Connects to Jesus Christ
Jesus is the living Word (John 1:1), and Revelation is His message to the Church. Adding to His Word is, in effect, denying that He has said enough. But He has said enough. Through His life, death, resurrection, and promises, Jesus has fully revealed the way of salvation.
He is the fulfillment of the Law and the Prophets. Everything points to Him. The entire Bible leads to Jesus—and Revelation shows Him as the returning King. Nothing more needs to be added, because He is everything.
Hebrews 1:1-2 says that in the past, God spoke through the prophets, but now He has spoken through His Son. Jesus is the final Word, and Revelation is the closing chapter of His message. To add to that is to ignore His authority and insult His sufficiency.
