How does Direct Experience confirm Faith?

Sariputta once said to the Buddha:
It is to be expected,
Venerable Sir, that any Noble Disciple
who has faith,
who has aroused energy and established awareness, and who is concentrated,
will understand reality thus:
This Samsara is
without discoverable beginning!
Any first point for beings roaming and wandering on, blinded by ignorance and
bound
by
craving cannot ever be seen! But what can indeed be experienced
is the traceless fading and ceasing of ignorance,
this massive of darkness:
That is the peaceful state, that
is the supreme state ...
that is, the stilling of
all mental construction,
the relinquishment of all acquisition,
the elimination
of all craving, complete disenchanting
disillusion, final ceasing, Nibbāna!
That unique comprehension of his is rooted in his ability
to understand Sir!
And, Venerable Sir, when he has strived again and again along this very way,
repeatedly
recollected in that way, again and again concentrated his mind in
exactly this way,
over and over
again understood only this in this very way,
then that
Noble Disciple
gains complete faith thus: Regarding things that I
previously had only heard about,
now I dwell having contacted them with my
body, and having perforated them by
understanding; I now see and directly
experience! That conviction, Venerable
Sir,
is his ability of
faith
working...
Sadhu! Sadhu! Good, true and well spoken
Sariputta!
