What does Isaiah 66:5 mean?

Listen to what the Lord says, you who tremble at his word: Your own people hate you and push you away because of my name. They say, 'Let the Lord show his glory so we can see your joy.' But they'll end up ashamed. Isaiah 66:5 - Modern Text Bible

(God encourages those who are rejected or mocked for their faithfulness. Even if others look down on them, God will vindicate them in the end.)
