What does the Bible say about the gathering of believers in heaven?

Revelation 7:9-10 reveals a glorious vision of a great multitude that no one can number. This multitude consists of believers from all nations, tribes, and tongues, standing before the throne of God and the Lamb, clothed in white robes and waving palm branches in joy. This depiction not only emphasizes the inclusive nature of God's redemption, encompassing believers from every background, but also assures us that all the elect, chosen before the foundation of the world, will be gathered to worship God eternally. It serves as a reminder that, despite the trials we face in this life, there is a glorious future awaiting all who are in Christ, where eternal fellowship with Him and with one another will be our reality.
