People go to hell because of their deliberate sins.
No one ever went to hell because of invincible or inculpable ignorance.
People go to hell for rejecting God’s gift of salvation offered in and through a relationship with Jesus.
Yes, sin is the reason we are condemned to hell but if all someone did was sin ONE sin and live an otherwise perfect life, they’d still be going to hell.
It took only one sin for Adam and Eve to break their relationship with God and have Him promise a redeemer.
So even if it were possible to die not in an actual state of sinning, the record of our life testifies against us, unless that record is wiped clean and judicial pardon is granted.
Arthur..people go to hell because they do not have a Savior
