What a warning! – ‘If any man shall add unto these things, God shall add unto him the plagues that are written in this book. And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book.
This warning anticipates attacks on Scripture. It has nothing to do with mistakes made by those who sincerely try to translate or publish the word of God. It is obviously dealing with deliberate attempts to corrupt it. The enemies of the truth have certainly made such attacks. They have tampered with the text of Scripture; they have called into question the authenticity of its books which the church has received from the hands of the apostles and prophets as inspired Scripture; and they have added man-made traditions which prevent men from obeying God (Matthew 15:4-6). But most of all they have denied its truth, rejecting the power and authority of the Lamb, the way of salvation by grace alone, the satanic alliances of this corrupt world and the need for the church to engage in a struggle of life and death for the truth.
Can any have their name removed from the book of life? As in Revelation 3:5 the warning must be taken seriously. It must be taken seriously by believers and by unbelievers. In the case of the former, it will be the very means of preserving them from destruction. It will stress to them the enormity of what is at stake and how important is their respect for God’s revelation. Believers will heed the warning, and unbelievers will ignore it and in them the warning will be fulfilled in them.
