Well CURED in the blood of Christ....

"A Great Sin will certainly give a great turn to the life of a [professing believer].

If it be well cured* in the blood of Christ,
with that humiliation which the gospel requires,
it often proves a means of more watchfulness,
fruitfulness,
humility,
and contentation [satisfaction, reassurance],
than ever before the soul obtained.

If it be neglected, it certainly hardens the heart,
weakens spiritual strength,
enfeebles the soul,
discouraging it unto all communion with God,
and is a notable principle of a general decay."

~John Owen, from "The Effect and Strength of Indwelling Sin"
(as printed in "Overcoming Sin and Temptation," p. 387)
