Do you believe that Jesus, the Son of God, and God the Son, died for all of your sins the cross, was buried, and rose again on the third day, according to the Scriptures? (1st Corinthians 15:1-4)
If you believe this Gospel for even one moment, if you believe in Jesus, that Jesus did it all for you, and your good works before, during or after coming to faith in Jesus play zero part in your salvation, then you are permanently saved, and sealed forever for Heaven. (John 6:47, Ephesians 1:13,14)
If you do not believe in Christ, and you never believed in Christ, and you never do believe in Christ before you die, then you will go to Hell, a real physical Place of burning fire, to be tormented forever for your sins, and you will be removed from the presence of God forever.
This is the truth the Bible teaches about eternal salvation. Amen.
