Whether the evil of sin is an object of fear?

Objections

Objection 1 : It would seem that the evil of sin can be an object of fear. For Augustine says on the canonical Epistle of John (Tract. ix), that "by chaste fear man fears to be severed from God." Now nothing but sin severs us from God; according to Is. 59:2: "Your iniquities have divided between you and your God." Therefore the evil of sin can be an object of fear.
Objection 2 : Further, Cicero says (Quaest. Tusc. iv, 4,6) that "we fear when they are yet to come, those things which give us pain when they are present." But it is possible for one to be pained or sorrowful on account of the evil of sin. Therefore one can also fear the evil of sin.
Objection 3 : Further, hope is contrary to fear. But the good of virtue can be the object of hope, as the Philosopher declares (Ethic. ix, 4): and the Apostle says (Gal. 5:10): "I have confidence in you in the Lord, that you will not be of another mind." Therefore fear can regard evil of sin.
Objection 4 : Further, shame is a kind of fear, as stated above (Question [41], Article [4]). But shame regards a disgraceful deed, which is an evil of sin. Therefore fear does so likewise.
