How do we know Christ is all we need for salvation?

The sufficiency of Christ as the only means of salvation is a fundamental doctrine of the Christian faith. Paul articulates this in several letters, asserting that Christ is the end of the law for righteousness. This is crucial because it highlights that no works or human efforts are necessary or sufficient for salvation. In Ephesians 1, Paul notes that believers are chosen in Christ before the foundation of the world, emphasizing that salvation is a divine gift, not based on human merit. This reinforces the truth that Christ alone is sufficient for salvation—He is both the means and the end.
