What should Christians do in their day of trouble?

As highlighted in the sermon, the appropriate response for Christians in their day of trouble is to call upon the Lord. Psalm 20 opens with an assurance that God hears us when we call, and ends with a plea for divine intervention: 'Save, Lord!' (Psalm 20:9). This reflects a heart that understands its limitations and depends entirely on God's grace for deliverance. Moreover, acknowledging the fullness of God's promises equips believers to face their struggles with hope and strength derived from faith in Him, solidifying their reliance on His sovereignty.
