Chapter 15:1-4

Prepartion is made for the consumation of the Judgement with the introduction of seven angels who will empty the seven bowls ( 16: 1-21).

Smoke: See Is. 6:1-4 Glory: See Ex. 40:34,35; 1 Kings 8: 10,11.

The mercy seat is now inaccessible. No futher petitions or intercessions will be heard until the Final Judgement is completed.
God Himself commands the Final Judgement. (16:1)
