Why should we trust in God's mercy?

In verse 5 of Psalm 86, David declares, 'For you, Lord, are good and ready to forgive, and abundant in mercy to all those who call upon You.' God's readiness to forgive and His abundant mercy are first principles of our faith. They underscore the gospel message that Christ, in His richness, became poor for our sakes, highlighting the depth of His love and grace. Our invitation to come to Him, broken and needy, is based on this very assurance of mercy. When we understand our unworthy state, we find comfort and hope in knowing that God's mercy is not limited; it is always available for those who humbly seek Him.
