Preaching = Sin Discovery

From Tony Reinke, aka"Spurgeon," at Miscellanies comes this quote worthy of much meditation.

“That one main end of the Word of God,
and preaching,
is to discover this deceitful heart.
It’s to make us know ourselves;
compared therefore to a glass,
that will show a deformed man all his unloveliness,
and this is a glass,
not to the face but the heart;
all those hidden and unknown lusts may there be brought to light.
And the Ministry that is compared to light;
as the sunbeams discover those many thousands of motes in the air,
which the darkness concealed;
thus the Ministry,
in a powerful and soul-saving way dispensed,
will make thee see thyself to be that beast,
that devil,
yea to have that dunghill,
that hell in thy heart,
thou didst not perceive:
look then for this benefit by preaching,
not what may fit thy ear,
may please thy fancy,
but what may discover the dark corners of thy soul,
what may bring glorious light into thy breast;
that thou mayest cry out;
O Lord, how long have I lived and did not know myself!
I thought all was well,
everything was in quiet;
but now I am like the Syrian army,
that being by the Prophet stricken blind,
and thought they were guided to their own camp,
as soon as ever they had their eyes opened,
they found themselves in the midst of the enemy’s camp:
Thus thy eyes being opened,
thou seest thyself to be in the power of all thy sins,
all thy enemies and the curses of God.”
