In your theology, no one knows for sure.And I answered. You know how He did not die for their sins? They remain in their unbelief. How do you know he died for yours?
Scripture does state that Christ died for the ungodly sinful enemies of God, of which I am one.
Rom 5:6 For when we were yet without strength, in due time Christ died for the ungodly.
Rom 5:7 For scarcely for a righteous man will one die: yet peradventure for a good man some would even dare to die.
Rom 5:8 But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us.
Rom 5:9 Much more then, being now justified by his blood, we shall be saved from wrath through him.
Rom 5:10 For if, when we were enemies, we were reconciled to God by the death of his Son, much more, being reconciled, we shall be saved by his life.
