You do not have to go to Hell.
Read: Romans 10:9-13
9 If you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. 10 For it is by believing in your heart that you are made right with God, and it is by confessing with your mouth that you are saved. 11 As the Scriptures tell us, “Anyone who trusts in him will never be disgraced.”[a] 12 Jew and Gentile[b] are the same in this respect. They have the same Lord, who gives generously to all who call on him. 13 For “Everyone who calls on the name of the LORD will be saved.”
