DLIFE 8, 20-21 - In proportion as a person shuns evils as sins, in the same proportion he does goods, not from himself but from the Lord.

DLIFE 20-21
It is plainly evident from all this that in proportion as a person shuns evils,
in the same proportion is he with the Lord and in the Lord;
and that in proportion as he is in the Lord,
in the same proportion he does goods,
not from self but from Him.
From this results the general law:
IN PROPORTION AS ANY ONE SHUNS EVILS,
IN THE SAME PROPORTION HE DOES GOODS.

Two things however are requisite:
first, the person must shun evils because they are sins,
that is, because they are infernal and diabolical,
and therefore contrary to the Lord and the Divine laws,
and secondly, he must do this as of himself,
while knowing and believing that it is of the Lord.
