The Bible teaches that salvation comes only through faith in Jesus Christ because, according to Christian doctrine, he was the Son of God who came to earth to redeem humanity by offering himself as a sacrifice for sins. The Bible states that "there is no other name under heaven given to mankind by which we must be saved" (Acts 4:12). Christians believe that salvation cannot be achieved through good works alone, but only through faith in Jesus Christ, who is the way, the truth, and the life (John 14:6). They also believe that Jesus' death and resurrection made it possible for humans to have eternal life with God. These teachings are at the core of Christian faith and are based on the belief that Jesus Christ is the savior of the world.
