What does 2 Corinthians 12 teach about weakness?

In 2 Corinthians 12, Paul illustrates a profound truth: our weaknesses are not points of shame but avenues through which Christ's power can be made manifest. Paul recounts his own struggles, emphasizing that when he is weak, then he is strong, for it is in his weakness that he relies more fully on Christ's strength. Through this dependency, believers are reminded that they do not achieve righteousness or strength through their own efforts but through the grace and power of Christ. This is a fundamental aspect of Reformed theology, which affirms that all of life and faith are sustained by God's sovereign grace, particularly in our weaknesses.
