If you would like to be sure that you are Saved,
Jesus, I believe that you are the Son of God, that you died for me, that God raised you from the dead and that you are alive today. Save me so that I can live in the light of God. I believe that my sins are forgiven and that I don't have to fear death anymore. I have moved from darkness into the light. Thank you, Jesus, for Eternal Life.
Now tell someone about what you have done.
If you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved. (Romans 10:9)
