Jesus Christ is our substitute because He fulfilled the law perfectly and bore the punishment for the sins of His people (Isaiah 53:5).
In the context of worship and sacrifice, the sermon emphasizes that every individual born into this world is a sinner and cannot approach a holy God without a sufficient substitute. Jesus Christ, fully God and fully man, is the perfect mediator who took upon Himself the guilt and punishment for the sins of His people. Isaiah 53:5 describes Him as 'wounded for our transgressions' and 'bruised for our iniquities.' His sacrificial death satisfied God's justice, allowing His chosen people to be reconciled with God. This central theme of substitutionary atonement permeates the entirety of scripture as it showcases the extent of God's love and grace towards those He has redeemed.
