TCR 358, 359,361, 365 - how faith & charity become spiritual

TCR 358
The reason why a person is given life
by approaching the Lord
is that the Lord is life itself,
not only the life of faith,
but also the life of charity.

TCR 359
. . . a person can only acquire by his own efforts natural faith,
which is a firm belief that a thing is so
because an authoritative person so declared it.
He can also acquire only natural charity,
 which is working in someone's favor
for the sake of some reward.
These two contain man's self,
and there is no life as yet from the Lord.
Still a person by either of these
prepares himself to receive the Lord.
In so far as he prepares himself,
so far does the Lord come in
and make his natural faith spiritual,
and likewise his charity,
and so make both living.
These results follow
when a person approaches the Lord
as the God of heaven and earth.

TCR 361 [2]
In so far as a person's faith and charity become spiritual,
so far is he withdrawn from the self
and does not have in view himself,
a reward or recompense,
but only the delight of perceiving the truths
which make up faith
and of performing the good actions which make up love.
In so far as that spirituality is increased,
 so far does that delight become blessedness;
this is the source of his salvation,
which is what is called everlasting life.

TCR 365
. . . since the life of Divine wisdom is the essence of faith,
and the life of Divine love is the essence of charity.
Therefore, when the Lord is present
with His own particular attributes,
namely Divine wisdom and Divine love,
He is also present
with all the truths which make up faith
and all the kinds of good which make up charity.
For faith means every truth
which the Lord enables a person
to perceive, think and speak,
and charity means every kind of good
for which the Lord inspires an affection,
and which the person consequently wills and does.
