A few posts above, when were discussing about Ezekiel 18. I quoted this:
Ezek 18:
20The soul who sins is the one who will die. A son will not bear the iniquity of his father, and a father will not bear the iniquity of his son. The righteousness of the righteous man will fall upon him, and the wickedness of the wicked man will fall upon him.
21But if the wicked man turns from all the sins he has committed,
keeps all My statutes, and does what is just and right, he will surely live; he will not die.
22None of the transgressions he has committed will be held against him. Because of the righteousness he has practiced, he will live.
And you said, this means a persons own righteousness.
