Christ is our salvation (Romans 1:16). The gospel is simple and clear for all to understand. Christ alone died for our sins according to the Scripture. He was buried and raised from the dead on the third day (1 Corinthians 15:1-4).
Christ is our salvation freely offered to all people everywhere without exception. Christ is offered for all to receive, calling upon the name of the Lord (Romans 10:13). Believers confess Jesus as our Lord risen from the dead (Romans 10:9).
Jesus commanded His disciples to preach the gospel to everyone (Matthew 28:19; Mark 16:15; Luke 24:47). Christ offers himself to all people in all nations. Believing in Jesus our Lord is receiving him (John 1:11-12).
Christ is the salvation of every true believer from the condemnation of sin (John 3:17). Believers are saved from everlasting punishment (Matthew 25:46). Believers are delivered from the kingdom of darkness into the kingdom of light (1 Peter 2:9).
Christ is salvation received by faith or rejected by unbelief (John 3:18). Those who reject the gospel of Christ are judged and perish in their own unbelief (John 3:16). That's because they believe not the Son of God (John 3:36).
