What does 1 Thessalonians 2:16 mean?

They try to keep us from speaking to people outside their group, so those people can’t find life. They keep adding to their wrongdoing, and now it’s like God’s patience has run out for them. 1 Thessalonians 2:16 - Modern Text Bible

(Paul is saying that persistent opposition to the gospel has consequences, and that God’s judgment is coming for those who keep blocking others from hearing the good news.)
