How do we know Christ is our shield?

Christ fulfills the role of our shield by stepping in to receive the just punishment for our sins. This is highlighted in the sermon where it states that Jesus stands between the believer and the justly offended majesty of God, absorbing the blows of divine justice in our place. As stated in 2 Corinthians 5:21, 'For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.' It is through faith in Him that we find true refuge and safety, as He takes upon Himself the wrath of God meant for sinners, thereby becoming our shield and defender.
