To do goods and not to fight against evils is to do goods from self and not from the Lord.
It is believed by many that they will be saved because they have done goods, as that they have given to the poor, benefitted their neighbor, acted sincerely and justly in their duty and work, and yet have never fought against the evils opposed to their goods; believing that thus evils are removed. It appears to them, moreover, as if goods removed evils; saying in heart, “If I do good then I shall avoid evil.” Nevertheless the case is as follows:
that such a one does good from obedience to the precepts of the Lord, yet not from the Lord but from himself, thus not from any spiritual law except only apparently, but from a moral and civil law actually.
In this case his evils nevertheless remain; for although he does not do them, yet he is not averse to them. Consequently when the love of evil with its delight returns, he does not resist the evil, but either excuses it and does it, or omits doing it on account of himself and the world; moreover, he does not then know that it is evil.
The case is otherwise when he fights against evil from the spiritual law; for, insofar as he does this, he censures evil, and he then loves good and its truth; and in proportion as he does good from the Lord and not from himself, in the same proportion the Lord, by the good and truth in the man, removes his evils.
