What does Psalm 61:8 mean?

Anticipating God's answers to his prayers (Psalm 61:1–2, 6–7), David vows to worship the Lord and continue to obey His commands (Psalm 18:21–22).

Believers should follow David's example: praising the Lord and obeying Him every day. In his letter to the Colossians, Paul combines both singing and obedience in his instructions. He writes, "Let the word of Christ dwell in you richly, teaching and admonishing one another in all wisdom, singing psalms and hymns and spiritual psalms, with thankfulness in your hearts to God. And whatsoever you do, in word or deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him" (Colossians 3:16–17). As believers study the Bible, fellowship with other believers, and look at creation, they become increasingly aware of the marvelous things God has done for them. This awareness prompts them to praise and obey Him. Even when circumstances seem dire, they can do what Paul and Silas did in prison: sing praises to God, who is infinitely greater than our circumstances (Acts 16:23–25).
