What does it mean to be part of the 'you all' in Revelation 22:21?

In Revelation 22:21, the phrase 'you all' is a direct reference to the believers—the elect who are assured of God's grace. This assurance is rooted in the understanding that those included in the 'you all' are the ones who have been written in the Lamb's Book of Life, as noted in Revelation 21:27. This book contains the names of those whom God has foreknown and predestined for salvation, as elaborated in Romans 8:29-30, meaning that those who belong to this group can rest in the certainty of their salvation.

Being part of the 'you all' reinforces the idea that salvation is not based on personal merit but on God's sovereign choice and grace. Every believer can claim this promise of grace and fellowship with Christ, underscoring the unity and security found in the body of Christ. Therefore, when believers recognize that they are among the 'you all,' it brings encouragement and deepens their relationship with the Lord, affirming their identity as His chosen people.
