AC 8639 - what we need to know so we can do

AC 8639
... he who does not know
that the Lord is the Saviour of the human race,
cannot have faith in Him,
love Him,
and thus do good for His sake.
He who does not know
that all good is from Him,
cannot think that his own righteousness
and his own salvation are from Him,
still less can he will it to be so,
thus he cannot live from Him.
He who does not know
that there is a hell,
and that there is a heaven,
nor that there is eternal life,
cannot even think about the life of heaven,
nor apply himself to receiving it;
and so in all other things.
