Why is Christ's atoning work significant for believers?

The significance of Christ's atoning work for believers cannot be overstated; it is the very foundation of our faith and relationship with God. As articulated in John 17, Jesus expresses His purpose in coming to Earth, highlighting that He glorified the Father by completing the work given to Him. This work culminated in His sacrificial death on the cross, through which He bore the sins of His chosen people. The essence of Christ's redemptive work is that it does not merely make salvation possible; rather, it accomplishes the actual salvation of those the Father has given to Him. As such, the atonement is not just a mere transaction but a profound demonstration of love, mercy, and divine justice, fulfilling the covenant of grace. Hence, believers find their assurance and hope in the completed work of Christ, which secures their eternal life and glorification.
