What does Ezekiel 33:13 mean?

If I tell a good person they'll live, but they start trusting in their own goodness and then do wrong, none of their good deeds will matter anymore. They'll die because of the wrong they've done. Ezekiel 33:13 - Modern Text Bible

(Relying on past good deeds doesn't excuse present wrongdoing. God cares about ongoing choices, not just a record of good behavior.)
