How do we know that Christ is the needed gift for salvation?

The necessity of Christ as the gift for salvation springs from humanity's profound need for reconciliation with God. Scripture asserts that all have sinned and fall short of the glory of God (Romans 3:23). Thus, the only solution for our sin is Christ, who 'came not to destroy the law but to fulfill it' (Matthew 5:17). He lived a perfect life in accordance with God's law and, through His sacrificial death, took upon Himself the full penalty for our sins, which is death (Romans 6:23). This fulfills the requirement of justice while simultaneously extending grace to the undeserving. Therefore, acknowledging our sin and the law's demands emphasizes the significance of the gift of Christ, highlighting His role as both redeemer and savior.
