How do we know grace is sufficient for our weakness?

Paul's statement in 2 Corinthians 12:9 is a profound revelation of grace. He learned through his own struggles that when he feels most weak, God's grace is where strength is found. This indicates a majestic inversion where worldly understandings of power and success are turned upside down. Instead of depending on our strength or accomplishments, God invites us to embrace our weaknesses, where His grace flows abundantly. Moreover, Romans 6:14 assures us that sin does not dominate those who are under grace, providing further assurance that grace transforms our relationship with sin and empowers us to live for God. Thus, relying on His grace and the righteousness of Christ is essential in the life of a believer.
