We know Christ is able to save us because He is powerful and capable, as expressed in Paul's assurance, 'I am persuaded that he is able' (2 Timothy 1:12).
The assurance of Christ's ability to save is deeply rooted in the claims of Scripture, including 2 Timothy 1:12, where Paul expresses his confidence in Christ's power to keep what he has committed to Him. This ability is not merely a theoretical concept; it reflects the very nature of Christ as the mighty Savior who accomplishes what He sets out to do. According to Reformed theology, Christ's atoning death was not uncertain—He came to save His people definitively. This contrasts with misunderstandings of Christ as just a potential savior, dependent on human choice. Instead, Christ actively seeks and saves the lost, demonstrating His sovereignty in salvation. His resurrection victory over death further assures us that He can and will preserve His people eternally.
