What does the Bible say about casting our burdens on the Lord?

Psalm 55:22 states, 'Cast thy burden upon the Lord, and he shall sustain thee.' This verse powerfully illustrates the believer's call to trust in God's strength rather than relying on our own. The burdens we carry can often feel weighty and overwhelming, but the psalmist reassures us that by casting them onto the Lord, we can find peace and support. David, in this psalm, expresses deep sorrow due to betrayal and adversity, yet ultimately declares his reliance on God to sustain him through his trials. This reflects the broader biblical theme of God's faithfulness and ability to support His people during life's challenges.
