How do we know that Jesus Christ's sacrifice is sufficient for salvation?
Answered in 1 source
The sufficiency of Christ's sacrifice is proven by His inability to fail in saving those for whom He died.
Scripture teaches that Jesus Christ’s death was sufficient for the eternal salvation of His people, as seen in passages like 2 Corinthians 5:21. When Christ was made sin for us, He fully bore the penalty of sin, satisfying God’s justice while granting believers pardon. The assurance that God cannot condemn those for whom Christ died (Romans 8:34) underscores the efficacy of His sacrifice. It is impossible for God, who is just, to punish sin twice. Thus, the believer's confidence rests not in their own works, but solely in Christ’s accomplished work on the cross.
