How do we know that Christ's obedience is sufficient for salvation?
Answered in 1 source
Christ's obedience is sufficient for salvation because, as the last Adam, His righteousness is credited to believers, providing them with justification before God (Romans 5:19).
The sufficiency of Christ's obedience for salvation is rooted in the doctrine of imputation. In Romans 5, Paul argues that just as Adam's disobedience brought sin and death, Christ's obedience unto death provides righteousness and life for those in Him. His life of perfect obedience fulfills the requirements of the law, thus providing a righteousness that is not our own. When we place our faith in Christ, we receive the benefit of His obedience and sacrifice. This means that believers are justified before God solely based on Christ’s righteousness, not their own works or merits. This truth is fundamental in sovereign grace theology, emphasizing that salvation is through faith alone in Christ alone.
