OSAS And Rev. 22:19

Q. I believe in OSAS (if it weren’t true, I would be doomed), but someone in my church said he didn’t believe it because of Revelation 22:18-19: The person said that if God takes away someone’s part of the book of life, then they already must have been written in it and would have lost their salvation.  What do you think?

A. I think that’s a really flimsy excuse to discard all the clear passages that confirm our security.  According to John 3:16 every one in the world has a part in the Book of Life.  All we need to do is believe to receive it, and in Ephesians 1:13-14 we’re told that as soon as we do, God guarantees our salvation, no matter what.  In Rev. 22:19 John was saying that if a person changes the Book of Revelation it would mean that they aren’t a believer and God would make sure that they never become one.
