What did Jesus Christ accomplish through His death?

The death of Jesus Christ was not merely a tragic event, but the pivotal act of redemption for His people. As indicated in John 6:37, all whom the Father gives to Him will come to Him and He will not cast them out. His death satisfied the justice of God for the sins of the elect, taking their iniquities upon Himself. This is reflected in the concept of imputation, where the sins of believers were accounted to Christ, and in turn, His righteousness is imputed to them. Consequently, all of salvation is conditioned upon Christ's work and not on human effort. Romans 8:33 assures that God justifies those who are His, confirming that the work of redemption was complete and satisfactory through His death alone.
