What does Psalm 57:11 mean?

This repeats the refrain David wrote in verse 5. He calls for the Lord's praise to spread all over the world. This is a fitting conclusion to a song written by a man the midst of danger (Psalm 57:1–4, 6; 1 Samuel 19:1–2; 22:1; 24:2–3) yet steeped in deep faith (Psalm 57:7–10). The risks around him did not dull David's confidence in the Lord's promises (Psalm 57:3). His reaction to hardship shows how believers can endure tragic circumstances with grateful hearts (1 Thessalonians 5:8).

God's glory is a frequent theme in the Bible. When an angel announced the birth of Jesus to a group of shepherds, the glory of the Lord shone around them (Luke 2:9). When Jesus stood at the top of a high mountain with three of His disciples, "he was transfigured before them, and his face shone like the sun, and his clothes became white as light" (Matthew 17:2). Later, the apostle John wrote, "we have seen his glory, glory as of the only Son of the Father, full of grace and truth" (John 1:14). Someday a remnant of Israel and saved Gentiles will see God's glory (Isaiah 60:2–3). It will happen when Jesus reigns on earth. Paul testified that Christians would appear with Jesus in glory (Colossians 3:4). When the New Jerusalem descends from heaven, it will have the glory of God, and its radiance will resemble a rare jewel (Revelation 21:10–11). God's glory will make the New Jerusalem and earth bright and beautiful forever.
