A person who knows that they are in need of salvation, must also know that it is available. This happens when the person hears the gospel. The gospel is the news that Jesus has died and risen and promises eternal life to those who receive Him. The person then believes this message and responds. Various groups of Christians see this response in different ways. The Catholic and Orthodox churches, and some Restoration Churches say that the required response is Baptism. Other Protestants suggest a prayer to "ask Jesus to enter their heart (life)". In American evangelism, sometimes the suggested response has been to go to the front of a church in a public declaration of faith. St. Paul seems to have set down the proper response in his letter to the Romans, Chapter 10 verse 9. "if you confess with your mouth “Jesus is Lord” and believe in your heart that God raised him from the dead, you will be saved". Christians believe that the proper response to Jesus brings about justification, (forgiveness of sins), and begins the process of sanctification.
