Whoever will listen let them listen, and whoever will refuse let them refuse

Ezekiel 3:16-27
Son of man I have made you a watchman for the people of Israel so hear the word I speak and give them warning from me.
I will make your tongue stick to the roof of your mouth so that you will be silent and unable to rebuke them, for they are a rebellious people. But when I speak to you, I will open your mouth and you shall say to them, 'This is what the Sovereign Lord says,' "Whoever will listen let them listen, and whoever will refuse let them refuse; for they are a rebellious people."
They will learn it first through the terrors of judgment. Afterward they will see his power to restore and renew.
The meaning seems to be that Ezekiel would be dumb except on the occasion when God had a message for him to give. Was he forbidden to speak or did he actually lose the power of speech? Either way, the utterance he did make had added. Not until news reached of the fall of Jerusalem did  he speak normally again.
Why?
Ezekiel was assigned to be a watchman for the people of Israel. His mission is warning his people, if he did God will not hold him accountable for their blood. All of of the Christan has the mission to tell or warning others away from the sins.
Preach gospel is not pressure for whoever will listen let them listen, and whoever will refuse let them refuse.
How?
Don't forget the mission I am in this world to deliver gospel to other and do good witness among people.
