What does Isaiah 12:4 mean?
Isaiah has written what might be called a personal response to the Lord from God's people (Isaiah 12:1–2). On the day when their king, the Messiah, establishes His rule over the entire earth, they will joyfully declare thanks to Him. They will also enjoy His gracious salvation (Isaiah 12:3). Now he emphasizes that they will also turn and declare His praise before the world. They will call everyone to join them. The Lord's people won't keep their worship a secret; they will want the world to join in and praise God's name.Who better than the people of Israel to tell of God's mighty works at this moment in history? They will proclaim His greatness and power for thousands of years. As well as His grace to them, through the Messiah, even with their unfaithfulness to Him. Who will not listen to their story and join in the praise of the Lord?
