The death and resurrection of Jesus Christ ultimately solved the problem of man's separation and alienation with God because of sin by removing it (Psalm 51:5; Romans 3:10-12, 23; 5:12). Man is guilty before a holy God for breaking his divine law and justly deserves death (James 2:10; 1 Peter 1:16). Additionally, man's heart and the world in which he lives are corrupted and infiltrated by sin (Jeremiah 17:9; Mark 7:21-23; 1 John 2:16). Man tries to find happinesss, meaning, and purpose in life apart from God, but this is impossible for those who sin shall die (Ezekiel 18:4, 20). Since man cannot save himself (Romans 3:20; Ephesians 2:1-3), God must do so through Jesus Christ, our Lord and Savior (Romans 6:23). The gospel is the good news that the sinless and perfect man Jesus Christ sacrificed himself for us, taking upon himself our sins, "so that in him we might become the righteousness of God" ( 2 Corinthians 5:21). We could have never satisfied God's wrath for our sin and kept God's perfect laws ourselves, so Jesus did this for us (propitiation) by redeeming us from the curse of the law (Galatians 3:13).
