St Augustine did believe that Original Sin imperils the salvation of our souls. How, then, can the Soul achieve Salvation? Augustine, following St Paul, believed that this was possible only through the Grace of God. Because Man is so sinful, nobody deserves this Grace; it is therefore unmerited. But God had offered it to all mankind when He sent Jesus to take upon himself the sins of the world. It was an offer which, because men had free will, they could reject; and if they did so, they lost the chance of Salvation. The Latin word for loss is damnum; Damnation originally meant simply the loss of Salvation. That loss was terrible enough even if it was not accompanied by the eternal pains of hellfire. Salvation was impossible without the Grace of God: mired as he was in sin, Man could not achieve it by his own efforts.
But St Augustine went further than this: some men are predestined to exercise their Will to accept the offer of Grace and others are predestined to reject it. God, being omniscient, foresees, but does not determine who will accept His Grace and who will not.
Those who accept the help of Grace are helped in their struggle against Sin; those who decline it reject it and are enslaved by Sin.
Now why would anyone exercise his Free Will to reject Grace? The implication of Augustine’s teaching is that the capacity to use our Free Will to choose or to reject the offer of Grace, though very small in all of us, is smaller in some people than it is in others. He seems to suggest that some people are constitutionally capable of using the little Will they have to accept the Grace which then strengthens that Will further. The Will of others is so weak that they cannot even take that step.
An analogy would be of men in danger of drowning in the middle of the ocean. They can all swim a little; but none of them have the capacity to reach the far-off land by swimming. They see the captain of a distant liner launch a lifeboat which can take them to salvation. The current flows strongly in the opposite direction; even so, there are some swimmers who are constitutionally capable of reaching the lifeboat, whose crew will then help them to reach the liner. But there are some who, though they do try, are just too weak: the current sweeps them away. (Even the suggestion that constitutional strength or weakness are involved may sometimes be inappropriate: the strong swimmer may be strong because he has freely chosen to take a lot of exercise in the swimming pool; the weak swimmer may be weak because he has freely chosen to be a couch-potato instead.)
