And they keep on crying with a loud voice, saying: ‘Salvation we owe to our God, who is seated on the throne, and to the Lamb.’

Revelation 7:9, 10,

They acknowledge the enthroned God of heaven as the Universal Sovereign over all creation. They acknowledge the Messiah Jesus as “the Lamb of God that takes away the sin of the world” and admit that they owe their salvation to God through his once “slaughtered” Lamb and, by faith and obedience, “they have washed their robes and made them white in the blood of the Lamb.”
