The assertion was made that “Christ is seen blotting names out,” but in your verse from Revelation we see that Christ says He will NOT blot names out.
Exodus 32:31-33 (King James Version)
31And Moses returned unto the LORD, and said, Oh, this people have sinned a great sin, and have made them gods of gold.
32Yet now, if thou wilt forgive their sin--; and if not, blot me, I pray thee, out of thy book which thou hast written.
33And the LORD said unto Moses, Whosoever hath sinned against me, him will I blot out of my book.
Psalm 69:27-29 (King James Version)
27Add iniquity unto their iniquity: and let them not come into thy righteousness.
28Let them be blotted out of the book of the living, and not be written with the righteous.
29But I am poor and sorrowful: let thy salvation, O God, set me up on high.
