What does Psalm 126:3 mean?

In the prior verse (Psalm 126:2), the psalmist mentioned that the world outside of Israel was taking note of their restoration. That faithful Israelites could return to their homeland (Ezra 2:1) was thrilling enough. To know that the Gentile world was witnessing God's glory was an additional blessing. Here, the psalm follows the statement coming from "the nations" with the same truth spoken by the people of Israel.

Declaring God's influence in our lives is a key part of giving Him the glory He deserves. Jesus healed a demon-possessed man, who then wanted to travel with Jesus. Yet Jesus told the man to return home and declare how much God had done for him. In response, the cleansed man did just that (Luke 8:39). The simple testimony of the power of the Lord in a believer's life can be easily shared with others. Among the amazing things God has done for Christians are His provision of salvation (John 3:16–18), assurance of salvation (John 10:28), forgiveness of sins (1 John 1:8–10), transformation into a new person (2 Corinthians 5:17), the gift of the Holy Spirit (John 14:26; Ephesians 1:13–14), an eternal future with the Lord's abiding presence (Revelation 21:1–4), the privilege of prayer (Hebrews 4:16), peace with God (Romans 5:1), the peace of God (Philippians 4:7), Christian fellowship (Galatians 6:2), and the gift of the inspired Scriptures (2 Timothy 3:16–17).
