As Romans 10:9 declares, you must believe that Jesus died and rose from the grave on the third day for YOUR sins, and that Jesus is savior, messiah. You must confess Him as lord. If you want to do so, pray this prayer: "Lord Jesus, I receive you as my lord and savior. Forgive me for my sins. Wash me with your precious blood. I denounce the world and choose to be yours. Thank you for forgiving me and saving me, in Jesus name, Amen."
