To sin and not to blush!

(Thomas Brooks, "Heaven on Earth" 1667)

Only those things which are sinful, are shameful.

"Then, when I make atonement for you for all you have
 done, you will remember and be ashamed and never
 again open your mouth because of your humiliation,
 declares the Sovereign Lord." Ezekiel 16:63

When the penitent soul sees his sins pardoned, the
anger of God pacified, and divine justice satisfied,
then he sits down ashamed.

Sin and shame are inseparable companions.

A Christian cannot have the seeming sweet of sin, but
he shall have the real shame which accompanies sin.
These two God has joined together, and all the world
cannot put them asunder.

It was the vile and impenitent Caligula who said
of himself, "that he loved nothing better in himself,
than that he could not be ashamed."

A soul who has sinned away all shame, is a soul ripe for
hell--and given up to Satan! A greater plague cannot
befall a man in this life, than to sin and not to blush!
