Revelation 15 · a question people ask

"something like a sea of glass mixed with fire" (15:2). What is the sea of glass?

In the text

Here is what the chapter says of it. John saw "something like a sea of glass mixed with fire" (15:2), and those who overcame were "standing on the sea of glass, having harps of God" (15:2). The book doesn't say what the sea of glass is, and these notes don't either.

The verses

“I saw something like a sea of glass mixed with fire, and those who overcame the beast, his image, and the number of his name, standing on the sea of glass, having harps of God.”
Revelation 15:2 · World English Bible

From Favor's study of Revelation 15

Revelation 15: A sea of glass mixed with fire

The bowls come to the seven angels from "One of the four living creatures" (15:7), and the smoke that fills the temple is "from the glory of God and from his power" (15:8).

In Favor, questions like this come up right where they arise as you read, with the Hebrew and Greek behind the words and how the chapter leads to Jesus.
