What does it mean that Zion heard and was glad?

In Psalm 97:8, the statement "Zion heard and was glad" reflects the joy of God's elect when they receive the good news of salvation. Zion, representing the people chosen by God, rejoices at the proclamation of God's judgments that lead to redemption. This gladness stems from understanding Christ's atonement, which has established righteousness for His people. By hearing the gospel, the hearts of believers are quickened, and they experience the joy of being reconciled to God through faith in Christ. This is an encouragement that affirms their status as His beloved and holy people.
