God will abundantly bless the people who have been invited to celebrate the marriage of the Lamb. Only God should be worshipped. All his servants are on an equal basis.

Revelation 19:9-10

9 Then the angel said to me, “Write this: God will abundantly bless the people who are {whom he has} invited to the feast that celebrates Jesus, the one who is like a lamb, permanently uniting with his people, like someone [MET] marrying a wife.” He also said to me: “These words that God declares are true!” 10 I immediately ◄prostrated myself/knelt down► at his feet in order to worship him. But he said to me, “Do not worship me! I am just your (sg) fellow servant and the fellow servant of your (sg) fellow believers who tell people about Jesus. God is the one whom you should worship, because it is the Spirit of God who gives people the power to tell others about Jesus (OR, those who tell others about Jesus are truly declaring the words that the Spirit of God has given them)!”
