How do we know Christ alone is sufficient for justification?

The sufficiency of Christ for justification is rooted in His divine nature and finished work. In Romans 5:1, it states, 'Therefore being justified by faith, we have peace with God through our Lord Jesus Christ.' This underscores that Christ's blood is the basis for our justification, as He is the only one who fulfilled the law perfectly on our behalf. Moreover, Christ is the 'Lamb of God' who takes away the sins of the world (John 1:29), emphasizing that His sacrifice alone reconciles us to God. His faithfulness, obedience, and the acceptance of His righteousness distinguish our hope from the works of the law.
