How do we know that Christ's death was sufficient for our sins?

The sufficiency of Christ's death is grounded in the belief that He took our place on the cross, bearing the wrath of God meant for us. Romans 5:8 explains that while we were still sinners, Christ died for us; this reveals that His purpose was to satisfy God's justice for sinners who could not save themselves. Colossians 1:14 reinforces this idea, stating that in Christ we have redemption through His blood. Thus, His sacrificial death is sufficient to cover all sins and secure our reconciliation with God.
