What does the Bible say about why Christ came to earth?

According to Scripture, specifically in John 12:27, Christ declares, 'But for this cause came I unto this hour.' This statement encapsulates the reason for His incarnation and sacrificial death. He came with a specific mission to redeem sinners, fulfilling the eternal plan of salvation. This is further emphasized by the need for Christ to be the perfect substitute, as outlined in Isaiah 53, affirming that He bore our sins and iniquities. Without His death and resurrection, there would be no provision for our salvation and reconciliation with God.
