View sin in the red glass

(Thomas Watson, "The Beatitudes" 1660)

View sin in the red glass of Christ's sufferings.
The least sin cost His blood. Would you take a true
view of sin? Go to Golgotha! Jesus Christ poured out
His soul, as an offering for sin! Read the greatness
of your sin—in the deepness of Christ's wounds!
not Satan cast such a mist before your eyes—that
you cannot see sin in its right colors! Remember,
not only do great sins carry men to hell—but lesser
sins as well. "The wages of sin is death!" Every sin
is damnable. There is death and hell in every sin.
The least sin without repentance—will be a lock
and bolt to shut men out of heaven.
