How do we know that Christ died for our individual sins?

Isaiah 53:5 powerfully illustrates that Christ bore our iniquities and was wounded for our transgressions. The concept of substitutionary atonement is central to the Christian faith, affirming that Jesus took upon Himself the guilt of each believer. This means that He died for all the specific sins of His elect, ensuring that all who believe in Him are fully pardoned. His journey to Calvary was not just for a collective group but for each individual who is called by name, reinforcing the personal nature of salvation.
