This sermon is focused on Ephesians 6:10-14, specifically on the ‘breastplate of righteousness.’ Pastor Mark discusses the spiritual armor that Christians must wear to protect against Satan’s accusations and condemnations. Using illustrations from Albert Camus’ ‘The Fall’ and historical figures like General Patton, the Mark emphasizes the inherent human struggles with feelings of inadequacy and the need for God’s righteousness. He argues that true protection and acceptance come from Christ’s righteousness rather than personal achievements or religious zeal. Practical applications include recognizing the insufficiency of secular and spiritual breastplates, relying on Christ’s righteousness, and embracing grace amidst personal failings and hardships.
