The Bible Says Commentary on Revelation 4

The letters to the seven churches are concluded, but John’s vision continues. He is invited into the throne room where he encounters God on the throne, an indescribable sight.

John’s vision of the throne room continues as he describes the seven lamps and four creatures that worship the Lord. 

In the throne room of God, the twenty-four elders who sit on thrones also participate in worshiping God and submitting their authority under Him.
