How do we know Christ's sacrifice is effectual?

The effectiveness of Christ's sacrifice lies in its divine purpose and outcome. Scripture teaches that Christ died specifically for His sheep, as referenced in John 10:15 where He states, "I lay down my life for the sheep." The understanding of effectual redemption is rooted in the belief that Christ's death accomplished what it intended: the complete and absolute salvation of those whom the Father gave Him. If any for whom Christ died were to perish, it would imply a failure in His atoning work, contradicting the promises of God that assure believers of His complete and effective salvation.
