A mere cloak which covered
a heart full of unclean lusts!

(Archibald Alexander, "
The day of judgment")

"God does not view things the way men do.
 People look on the outward appearance, but
 the Lord looks at the heart." 1 Samuel 16:7

"You are the ones who make yourselves look right in
 other people's sight, but God knows your hearts.
 For the things that are considered of great value by
 people are worth nothing in God's sight." Luke 16:15

"He Himself knew what was in their hearts." John 2:25

"Lord, You know the thoughts of everyone." Acts 1:24

And as externally good actions will then be examined
by One who has a full view of the motives from which
they proceeded, and the end which the person had in
view--is it not certain that many religious actions
will then appear to have been mere hypocrisy? that
many actions, apparently just and benevolent, were
mere efforts of pride and selfishness? and that a moral
and blameless life in the eyes of men--was a mere
cloak which covered a heart full of unclean lusts

Our most intimate friends here, will be astonished when
they see our secret iniquities and wicked motives exposed
to view. The most detestable crimes will be unveiled in
those who passed through life without suspicion! O how
many secret murders, perjuries, thefts, blasphemies, and
adulteries--will then be brought to light! How much fraud,
injustice, cruelty, oppression, pride, malice, revenge will
then be unveiled!

"Almighty Lord, You test people justly; You know what
 is in their hearts and minds." Jeremiah 20:12

"You alone know the thoughts of the human heart.
 Deal with each person as he deserves." 1 Kings 8:39
