Paul is addressing the impartiality of God's judgment, emphasizing that it applies to all people, regardless of their ethnic or religious background. The mention of Jews and Gentiles reflects the cultural context of the early Christian community, where both groups were present. Paul is making it clear that God's justice is universal and that everyone is accountable for their actions. This serves as a warning against complacency and a reminder that wrongdoing leads to trouble and distress.
The phrase "first for the Jew, then for the Gentile" indicates the order of revelation and responsibility, as the Jews were the first to receive God's law. However, it also underscores that God's standards are the same for everyone, and no one is exempt from the consequences of evil actions. This message is a call to self-examination and a reminder of the importance of living a life aligned with God's will. It encourages believers to strive for righteousness, knowing that God's judgment is fair and just.
