Mark’s sermon highlights our universal need for God’s grace, using Paul’s life as an example. Paul was both "too bad" in his sins and "too good" in his self-righteousness, yet neither disqualified nor earned his salvation—it was God’s grace alone. Paul’s response to grace was a life of obedience and mission, showing that grace isn’t about comparison or merit but surrender. Mark urges us to remain grounded in the gospel, always returning to God’s grace as the foundation of faith, avoiding both despair and self-righteousness.
