According to evangelical Christian tradition, the most likely author of Revelation 21: 2-4 is the apostle John. He is traditionally believed to be the same John who authored the Gospel of John, the three epistles of John, and the book of Revelation. John is often referred to as the “beloved disciple” and was one of Jesus’ twelve apostles.

John is believed to have been exiled to the island of Patmos, where he received the visions that he recorded in the book of Revelation. In Revelation 21: 2-4, John describes a vision of the new Jerusalem coming down from heaven after the final judgment, where God dwells with his people and wipes away every tear from their eyes, ending all sorrow and pain.

Evangelical Christians view the book of Revelation as a prophetic and symbolic vision of the end times, emphasizing the ultimate triumph of God over evil and the establishment of a new heaven and new earth. The visions recorded in Revelation are seen as a source of hope and encouragement for believers, reminding them of the ultimate victory that awaits them in Christ.
