What does Isaiah 6:10 mean?
The bottom line of this verse is clear: The Lord is not interested in His people in Judah waking up. The time for them to change course and begin trusting Him has passed (Isaiah 6:9). He knows they are already too deeply committed to their false gods and sinful practices for repentance.Instead, the Lord wants the people of Judah to hear His message through a muffling filter in their hearts. This is a block their own sinful hearts have created. They don't want to hear from God, so whatever He says to them will fall on deaf ears. The people will not fully grasp the reality of their situation. Because they are stubborn, they will not trustingly turn to the Lord to be healed. The rejection of His message will be theirs, but the conditions of their hearts and minds will be God's doing.
The implications for Isaiah's life as the message-giver are becoming clear. He should expect very few people to respond to his message from the Lord.
