It will soften a stone!

--Thomas Watson, "The Mischief of Sin"

"The blood of Jesus cleanses us from all sin!"
1 John 1:7

Christ's blood is a SOFTENING blood.

There is nothing so hard, that it cannot be softened
by this blood. It will soften a stone! Water will
soften the earth—but it will not soften a stone; but
Christ's blood mollifies a stone. It softens a heart of
stone. It turns a flint into a spring. The heart, which
before was like a piece hewn out of a rock, being
steeped in Christ's blood—becomes soft, and the
waters of repentance flow from it.

"They will look on Me whom they have pierced and
mourn for Him as for an only son. They will grieve
bitterly for Him as for a firstborn son who has died."
Zechariah 12:10

How was the jailer's heart dissolved and made tender
when the blood of sprinkling was upon it! "Sirs, what
must I do to be saved?" Acts 16:30. His heart was
now like melting wax. God might now set whatever
seal and impression He desired, upon it.

"I will give you a new heart with new and right desires,
and I will put a new spirit in you. I will take out your
stony heart of sin and give you a new, obedient heart."
Ezekiel 36:26
