The responsibility of a watchman

Ezekiel 3:12-21
May the glory of the Lord be praised in his dwelling place - the sound of the living creatures.
After be lifted up and took away, Ezekiel went in bitterness and in the anger of his spirit, with the strong hand of the Lord upon him. He sat among them for seven days- overwhelmed.
Ezekiel be a watchman of the house of Israel.
Ezekiel have to say to a man no matter who is evil one or righteous one.
If he does not warm them, those men don't listen, they will die for their sin, but Ezekiel will be hold accountable for his blood. If he warmed them but those men don't listen, they will die for their sin, Ezekiel will have save himself.
The righteous thing he did will not be remembered when a righteous man turns from his righteousness and does evil.
Why?
What God's servant needs to do is may the glory of the Lord be praised.
Ezekiel received this mission with the bitterness and anger from the Lord, it was the feeling of the Lord turned to him. Ezekiel has the same feeling as the Lord.
Watchman is watch where has event and let people or dwelling people know. Giving warning to them.
Evil man turns from evil to righteous will save his life, but righteous man turns from righteous to do evil, he will die for his sin. For he has known what is right and evil. But he chose the evil, all he did will not be remembered.
How?
When I see anyone doing wrong or evil I should let them know with wisdom, or he may be saved, this is the love of the Lord and our job in this world. Usually we afraid the trouble don't like to do it. Do it with the wisdom of the Lord. Say what should I say.
