Those who are "victorious over the beast" are spiritually victorious. While most spiritual battles cannot be seen, the Book of Revelation pictures spiritual battles as openly occurring. (See: [[rc://en/tw/dict/bible/kt/spirit]] and [[rc://en/ta/man/translate/writing-apocalypticwriting]])
Scripture elsewhere indicates the earthly temple copied God's perfect dwelling place in heaven. Here John seems to refer to God's heavenly dwelling place or temple. (See: [[rc://en/tw/dict/bible/kt/heaven]] and [[rc://en/ta/man/translate/writing-apocalypticwriting]])
The Book of Revelation often describes heaven as a place where people sing. They worship God with songs. This illustrates that heaven is a place where God is always worshiped.
