What does Psalm 6:9 mean?

With great confidence David exclaims his faith that God has heard his cries. Believers should be encouraged by David's experience. The same Lord who answered his prayer also promises to answer ours.

Psalm 50:15 promises, "Call upon me in the day of trouble; I will deliver you, and you shall glorify me." James 5:13 asks, "Is anyone among you suffering?" The answer is, "Let him pray." Psalm 9:9–10 provides this assurance: "The LORD is a stronghold for the oppressed, a stronghold in times of trouble. And those who know your name put their trust in you, for you, O LORD, have not forsaken those who seek you." Prayer is listed as part of the spiritual armor with which God equips believers (Ephesians 6:10–18). Paul writes in Ephesians 6:18: "praying at all times in the Spirit, with all prayer and supplication." James 5:16 assures us, "The prayer of a righteous person has great power as it is working."
