What does Jeremiah 16:19 mean?

Lord, you are my strength and my protection, my safe place in times of trouble. Nations from all over the world will come to you and say, 'Our ancestors inherited nothing but lies, useless idols that can't help anyone.' Jeremiah 16:19 - Modern Text Bible

(Jeremiah expresses trust in God, foreseeing a time when people from every nation will recognize the emptiness of their old beliefs and turn to the true God.)
