What is the gospel of Christian salvation and where can we find its biblical teachings?

The gospel of Christian salvation is the good news about Jesus Christ and the salvation He offers to humanity. It centers on the belief that through Jesus’ life, death, and resurrection, individuals can be reconciled to God, forgiven of their sins, and granted eternal life. The key Elements of the Gospel of Christian Salvation includes the following revelation. Human Sinfulness: All humans have sinned and fall short of the glory of God (Romans 3:23). Jesus’ Sacrifice: Jesus Christ, the Son of God, died for our sins, was buried, and rose again on the third day (1 Corinthians 15:3-4). Faith and Repentance: Salvation is received through faith in Jesus Christ and repentance from sin (Ephesians 2:8-9, Acts 2:38). Grace of God: Salvation is a gift from God, not earned by human efforts (Ephesians 2:8-9). Eternal Life: Believers are promised eternal life with God (John 3:16). According to  John 3:16, “For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.” According to Romans 3:23-24, “For all have sinned and fall short of the glory of God, and all are justified freely by his grace through the redemption that came by Christ Jesus.” According to Ephesians 2:8-9, “For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God—not by works, so that no one can boast.” According to 1 Corinthians 15:1-4,“Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand; By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.  For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures” According to Acts 2:38, “Peter replied, ‘Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit.'” These passages collectively outline the core message of Christian salvation, emphasizing God’s love, human sin, Jesus’ sacrificial death and resurrection, and the necessity of faith and repentance
