How do we know that Christ's sacrifice is effective?
Answered in 2 sources
We know Christ's sacrifice is effective because it was made willingly and fulfills God's justice while securing salvation for believers.
The effectiveness of Christ's sacrifice can be affirmed through its duality of willingness and divine purpose. As noted in Ephesians 5:25, His voluntary offering - 'the just for the unjust' - indicates a selfless love that fulfills God's justice while upholding grace. Christ's obedience, demonstrated in His suffering, is further validated by Scripture, which indicates that the acts of atonement must come from a willing heart. The infinite worth of Christ, being fully God and fully man, underscores the sufficiency of His sacrifice to cover the sins of many and brings about true reconciliation between God and humanity. This is evidenced in Hebrews 10:14, which declares that 'by one offering He has perfected forever those who are being sanctified.'
