Whether one who has already obtained grace, can, of himself and without further help of grace, do good and avoid sin?

❌ Objection 1 : It would seem that whoever has already obtained grace, can by himself and without further help of grace, do good and avoid sin. For a thing is useless or imperfect, if it does not fulfil what it was given for. Now grace is given to us that we may do good and keep from sin. Hence if with grace man cannot do this, it seems that grace is either useless or imperfect.

❌ Objection 2 : Further, by grace the Holy Spirit dwells in us, according to 1 Cor. 3:16: "Know you not that you are the temple of God, and that the Spirit of God dwelleth in you?" Now since the Spirit of God is omnipotent, He is sufficient to ensure our doing good and to keep us from sin. Hence a man who has obtained grace can do the above two things without any further assistance of grace.

❌ Objection 3 : Further, if a man who has obtained grace needs further aid of grace in order to live righteously and to keep free from sin, with equal reason, will he need yet another grace, even though he has obtained this first help of grace. Therefore we must go on to infinity; which is impossible. Hence whoever is in grace needs no further help of grace in order to do righteously and to keep free from sin.
