If the New Testament Covenant guides your Christian life then the answer is most clearly no.
Once a Christians accepts Jesus as his savior he is born again and all he will ever need is his.
Revelation was a warning to the Christians of that day when it was time to get out of Dodge. The scriptures in Revelations do not pertain to today’s Christians.
Point out where the church is mentioned anywhere in Revelation after chapter 3.
Hint: It's not. There is no church on earth at that point.
