"And the LORD has laid on Him the iniquity of us all."
Isaiah the prophet spoke of a day coming when God the LORD would lay the sins of His covenant people upon a sacrifice. The Son of God Himself bore every believer's sins upon the cross. Isaiah foresees the Suffering Servant dying in the place of others.
Under the Old Covenant, a man would bring his animal sacrifice to the priest. Confessing his sin, he would then lay his hands upon the animal who would die in his place. Under the New Covenant, also known as the Everlasting Covenant (Hebrews 13:20-21), the LORD laid upon Jesus the sins of us all. The sinless Son of God died for the sins and iniquity of others. His own blood sealed the Everlasting Covenant forever!
LORD is God's covenant name. His covenant is the contract or agreement that God has made with everyone who trusts in Him. He guarantees that our sins are taken away by one sacrifice, even Christ crucified. There is salvation in no other (Acts 4:12), because only one man died for the sins of all God's covenant people.
As a believer in the Lord Jesus Christ, you can be sure that your sin debt is paid in full through Christ alone. The Gospel is clear. Christ died for our sins, according to the Scripture (1 Corinthians 15:1-4). The empty grave of Jesus proves that the LORD accepted His sacrifice for our sins. "By His death and endless life, Jesus saves."
You are saved not by what you do, but what God has done for you in Christ. "And the LORD has laid on Him the iniquity of us all." Faith receives the Gospel message, that Jesus died for all your sins (1 John 1:7). God's covenant word in Scripture is the sure witness to you as a believer in Jesus our Lord. Your sins were laid upon Jesus.
