His dreadful threatenings!

(Thomas Brooks, "Paradise Opened" 1675)

Sin and sorrow, iniquity and misery—always
go hand in hand.

"The wages of sin is death," Romans 6:23. Every
sinner is worthy of death. "Those who do such things
deserve death," Romans 1:32. If God is a just and
righteous God, then sin cannot absolutely escape
unpunished; for it is but "a just and righteous thing
with God"—to punish the sinner who is worthy of
punishment. As God must be just—so He must be
faithful. And if He must be faithful—then He must
carry out His threatenings against sin and sinners!

Look! As there is not a promise of God but shall surely
take place; just so, there is not a threatening of God
but shall surely take place. The faithfulness of God, and
the honor of God, are as much concerned in making good
of His dreadful threatenings—as they are concerned
in making good of His precious promises. God has given
it from His own mouth, that:
  "He will by no means clear the guilty;"
  "the soul that sins, shall surely die;"
  "the wickedness of the wicked shall be upon him;"
  "He will render to every man according to his deeds."

Will God abrogate His own laws—or will He dare men to
sport and play with His threatenings? Will not every wise
and prudent king look to the execution of their own laws?
And shall not that God, who is wonderful in wisdom, and
whose understanding is infinite—see all that all His laws
are put in execution against offenders? Surely yes!

"He will repay them for their sins and destroy them
 for their wickedness; the LORD our God will destroy
 them!" Psalm 94:23

"I will not look on you with pity or spare you; I will
 repay you in accordance with your conduct and the
 detestable practices among you. Then you will know
 that it is I the LORD who strikes the blow!" Ezek. 7:9

"When I sharpen My flashing sword and My hand grasps
 it in judgment, I will take vengeance on My adversaries
 and repay those who hate Me." Deuteronomy 32:41
