What does Psalm 31:19 mean?
David praises the Lord's lavish goodness. He does not place a measure on God's goodness, because it is immeasurable. It extends far beyond our need. His goodness abounds in times of trial as well as in times of plenty. Paul writes in Romans 5:17 about the abundance of grace. He also states, "Where sin increased, grace abounded all the more" (Romans 5:20).According to David, God's goodness is not merely plentiful, it is also always stockpiled and ready. This goodness, David says, is there for those who reverence God. The believer does not have to worry that the Lord's goodness will suddenly run out. Those who reverence Him also trust in Him for protection. David views the Lord's goodness as available "for those who take refuge in" the Lord. Nahum 1:7 affirms, "The LORD is good, a stronghold in the day of trouble; he knows those who take refuge in him."
Psalm 31:14–22 comes after David expressed sorrow over persecution and abandonment. Despite hardship, David tells God he still trusts in Him. He regarded the Lord as the foundation of his confidence. David asks the Lord to be forgiving and merciful, preserving him from the enemies who have attacked him. This passage celebrates God's forgiving nature, while looking back on prior instances of rescue.
Because God has rescued him in the past, David chooses to trust the Lord even when he is in danger. Neighbors and friends may abandon him, and enemies may plot, but David is confident he will be vindicated. He also calls on others to be firm and brave as they choose to trust in God.
