The righteousness of the righteous will be credited to them, and the wickedness of the wicked will be charged against them

Ezekiel 18:1-20

The parable: The parents eat sour grapes, and the children’s teeth are set on edge’. ?As surely as I live, declares the Sovereign Lord, you will no longer quote this proverb in Israel. For everyone belongs to me, the parent as well as the child—both alike belong to me. The one who sins is the one who will die.

Because he has done all these detestable things, he is to be put to death; his blood will be on his own head.

But suppose this son has a son who sees all the sins his father commits, and though he sees them, he does not do such things: 

He will not die for his father’s sin; he will surely live. But his father will die for his own sin, because he practiced extortion, robbed his brother and did what was wrong among his people.

The one who sins is the one who will die. The child will not share the guilt of the parent, nor will the parent share the guilt of the child. The righteousness of the righteous will be credited to them, and the wickedness of the wicked will be charged against them.

Why?
Everyone has to face his own sins or credit and take his own responsibility before the Lord.

The parable about the parents and their sons is not available before the Lord.

Everyone has to know even the environment may influence our minds and our way. But we still need to make decisions about what is right and what is wrong.

How?

Don't be a fool but be a man of wisdom, knowing the Lord is the beginning of wisdom.
