What is the meaning of Psalm 31:21?

Blessed be the LORD

• David opens with praise. He is not waiting for circumstances to improve; he blesses the LORD right in the middle of crisis (Psalm 34:1; 1 Thessalonians 5:18).

• The focus is on the covenant name “LORD,” reminding us that the God who spoke to Moses at the burning bush is personally involved (Exodus 3:14).

• Praise anchors the heart when everything else shakes (Psalm 18:46; Habakkuk 3:17-18).

for He has shown me

• David looks back at concrete evidence of God’s help, not vague optimism (Psalm 66:16).

• Testimony fuels trust: yesterday’s deliverance gives courage for today’s battle (2 Corinthians 1:10; Revelation 12:11).

• By using “me,” David personalizes God’s intervention; the Almighty cares for individuals (Psalm 40:1-3; Luke 12:6-7).

His loving devotion

• The phrase points to God’s steadfast, covenant love—unyielding, undefeatable (Psalm 136; Lamentations 3:22-23).

• Loving devotion combines affection and loyalty: He feels for His people and acts for them (Deuteronomy 7:9; Romans 8:38-39).

• In Christ we see this devotion perfected, as He lays down His life for us (John 15:13; 1 John 4:10).

in a city under siege

• The setting is extreme pressure: walls surrounded, supplies cut off, hope fading (2 Kings 6:24-27).

• God’s love is not hindered by locked gates or enemy armies (Psalm 46:4-7).

• When believers feel hemmed in—financially, relationally, culturally—this verse assures us that divine help reaches through every blockade (2 Corinthians 4:8-9; Hebrews 13:5-6).

summary

Psalm 31:21 celebrates a God who deserves praise because He steps into the tightest corners of life with steadfast, personal love. David’s experience becomes ours: even when besieged, we bless the LORD, recount His past faithfulness, rely on His unwavering devotion, and rest in the certainty that no siege can keep Him out.
