The warning against altering the prophecy is a solemn admonition found in the closing verses of the Book of Revelation. This warning serves as a critical reminder of the sanctity and inviolability of the divine revelation given to the Apostle John. The passage in question is Revelation 22:18-19, which states:

"I testify to everyone who hears the words of prophecy in this book: If anyone adds to them, God will add to him the plagues described in this book. And if anyone takes away from the words of this book of prophecy, God will take away his share in the tree of life and in the holy city, which are described in this book." (Berean Standard Bible)

Context and Significance

The Book of Revelation, also known as the Apocalypse, is the final book of the New Testament and the culmination of biblical prophecy. It is a revelation given by Jesus Christ to John, detailing visions of the end times, the final judgment, and the ultimate victory of God over evil. The warning against altering the prophecy underscores the importance of preserving the integrity of this divine message.

The admonition is twofold: it warns against both adding to and taking away from the words of the prophecy. This dual warning highlights the completeness and sufficiency of the revelation as it stands. The consequences of altering the prophecy are severe, reflecting the gravity of tampering with God's word. The plagues mentioned in Revelation are a series of divine judgments, and the loss of one's share in the tree of life and the holy city signifies exclusion from eternal life and the blessings of the New Jerusalem.

Theological Implications

From a theological perspective, this warning emphasizes the authority and finality of Scripture. It affirms the belief that the Bible, as the inspired word of God, is complete and sufficient for teaching, reproof, correction, and training in righteousness (cf. 2 Timothy 3:16). The warning against altering the prophecy serves as a safeguard against false teachings and distortions that could lead believers astray.

The passage also reflects the broader biblical principle of the inviolability of God's word. Similar warnings are found elsewhere in Scripture, such as in Deuteronomy 4:2 and Proverbs 30:6, which caution against adding to or taking away from God's commandments. These warnings collectively underscore the importance of fidelity to the divine revelation as it has been given.

Historical and Interpretive Considerations

Historically, the warning against altering the prophecy has been understood as applying specifically to the Book of Revelation. However, its implications have been extended to the entire canon of Scripture, reinforcing the belief in the closed nature of the biblical canon. This understanding has been pivotal in shaping the doctrine of biblical inerrancy and the rejection of extra-biblical revelations that claim equal authority with Scripture.

Interpretively, the warning serves as a call to humility and reverence in handling the word of God. It challenges believers to approach Scripture with a spirit of submission, recognizing its divine origin and authority. The warning also serves as a reminder of the responsibility of teachers and preachers to faithfully convey the message of Scripture without alteration or compromise.

In summary, the warning against altering the prophecy in Revelation 22:18-19 is a profound testament to the sanctity and authority of God's word. It calls believers to uphold the integrity of Scripture, recognizing its completeness and sufficiency as the final revelation of God's redemptive plan.
