To begin with, if a person is truly saved ALL of their sins are forgiven...Christ paid the penalty. The saved person has a clean slate and will not burn in Hell. There is no condemnation for those who are in Christ Jesus! For someone who has not repented and called upon the name of the Lord, it's a different story. God looks upon all sin the same; and the penalty for sin (unforgiven) is eternal death in a place called Hell!
