How do we know that trusting in God will help against fretting?

Trust in the Lord is foundational for overcoming fretting, as highlighted in Psalm 37:3, which says, "Trust in the Lord and do good..." By placing our confidence in God, we acknowledge His sovereignty and ability to meet our needs. This trust alleviates the burdens of worry by shifting our focus from earthly troubles to God’s providential care. As Romans 8:28 assures us, all things work together for good to those who love God, demonstrating that our trust in Him is rooted in His unchanging nature and faithfulness to His promises.
