ACC ~ 1 John 5 v18

THE EVIL ONE CANNOT TOUCH GOD’S CHILDREN. DIDYMUS THE BLIND: If it is true that when someone does what is righteous his power to do so comes from God, and if it is also true that righteousness and evil cannot live together, then it is perfectly clear that as long as a person does such things he is righteous and does not sin. But because this ability is given by grace and is not natural, John adds that the righteous person must watch out, so that evil will not touch him. COMMENTARY ON 1 JOHN.

NO ONE IS A CHILD OF GOD BY NATURE. ANDREAS: It may be true that the righteous person does not sin, but no one is a child of God by nature. This is why we avoid sin, not by the way in which we were made, which would make sin impossible for us,but by watching out that we do not fall into it. CATENA.

DAVID’S CASE. BEDE: Anyone born of God does not commit mortal sin, which we have defined earlier on. But mortal sin can also be understood to mean sin which retains its force right up to the moment of death, and those who are born of God do not commit that kind of error. David, for, example, confessed to having committed mortal sin, for how else can we regard such things as adultery and murder? But David was also born of God and because he belonged to that fellowship he did not sin up to his death, because when he repented he was regarded as worthy to receive forgiveness. ON 1 JOHN.
