A paradox is a true statement that appears to describe something impossible. A paradox occurs in verses 4-5: "We talk about your patience and faith in all your persecutions. We talk about the afflictions that you endure. This is a sign of God's righteous judgment." People would not normally think that believing in God while being persecuted is a sign of God's righteous judgment. But in verses 5-10, Paul explains how God will reward those who believe in him and how he will judge those who afflict them. ([2 Thessalonians 1:4-5](./03.md))
