====15:2 What is significant about the sea of glass here?==== 
The sea of glass here is covered with people, whereas when John first saw it in Rev 4:6 it was bare ('''cp''' Rev 4:1-6). At the time of Rev 4:6 only the church - represented by the twenty-four elders - and the Old Testament saints, were in heaven. 

In Re 15:2 the tribulation saints are in heaven and they now cover the sea of glass which is a transparent crystal - like pavement before the throne of God. It stretches out like a glittering sea of glass mingled with fire ('''cp''' Ex 24:10).
