Not if they keep the Law
You need to read the Book of Romans. For example, Romas 3:20 states Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin. No human descendant fathered by a man can keep the whole law, so no one can be saved by it. Only one man, Jesus, could keep it, and he was crucified in our stead. Basic Christian doctrine.
Christians are not addresses in the Book of Revelation after the third chapter.
