What does the Bible say about Jesus' work of salvation?

Scripture consistently affirms that Jesus accomplished the entire work of salvation on behalf of those chosen by God. As seen in John 6:39, He states, 'this is the will of Him who sent Me, that I shall lose none of all those He has given Me.' This underlines that Christ's mission was fully realized without human contribution. The notion that salvation requires human effort undermines the sufficiency of Christ's sacrifice, as He redeemed His people entirely through His death and resurrection. Verses like Titus 2:14 proclaim that He 'gave Himself for us to redeem us from all lawlessness.' Thus, understanding Christ’s role is crucial to recognizing the grace that He offers.
