There are many devices in a man's heart

(Philpot,  "Mans Devices and the Lord's Counsel")

"There are many devices in a man's heart;
 nevertheless the counsel of the Lord, that
 shall stand." Proverbs 19:21.

The devices of our heart are generally to find some
easy, smooth, flowery path. Whatever benefits we
have derived from affliction, whatever mercies we
have experienced in tribulation, the flesh hates and
shrinks from such a path with complete abhorrence.

And, therefore, there is always a secret
devising in a man's heart . . .
  to escape the cross,
  to avoid affliction, and
  to walk in some flowery meadow,
away from the rough road which cuts
his feet, and wearies his limbs.

Another "device in a man's heart" is, that he shall
have worldly prosperity; that his children shall grow
up around him, and when they grow up, he shall be
able to provide for them in a way which shall be best
suited to their station in life; that they shall enjoy
health and strength and success; and that there shall
not be any cutting affliction in his family, or fiery trial
to pass through.

Now these devices the Lord frustrates. What grief,
what affliction, what trouble, is the Lord continually
bringing into some families! Their dearest objects of
affection removed from them, at the very moment
when they seemed clasped nearest around their hearts!

And those who are spared, perhaps, growing up in such
a searedness of conscience and hardness of heart, and,
perhaps, profligacy of life, that even their very presence
is often a burden to their parents instead of a blessing;
and the very children who should be their comfort,
become thorns and briars in their sides!

Oh, how the Lord overturns and brings to nothing the
"devices of a man's heart" to make a paradise here
upon earth.

When a man is brought to the right spot, and is in a
right mind to trace out the Lord's dealings with him from
the first, he sees it was a kind hand which "blasted his
gourds, and laid them low;" it was a kind hand that swept
away his worldly prospects; which reduced him to natural
as well as to spiritual poverty; which led him into exercises,
trials, sorrows, griefs, and tribulations; because, in those
trials he has found the Lord, more or less, experimentally
precious.

"There are many devices in a man's heart."

Now you have all your devices; that busy workshop is
continually putting out some new pattern; some new
fashion is continually starting forth from the depths of
that ingenious manufactory which you carry about with
you; and you are wanting this, and expecting that, and
building up airy castles, and looking for that which shall
never come to pass; for "there are many devices in a
man's heart; nevertheless the counsel of the Lord,
that shall stand."

And so far as you are children of God, that counsel is
a counsel of wisdom and mercy. The purposes of God's
heart are purposes of love and affection toward you,
and therefore you may bless and praise God, that
whatever be the devices of your hearts against God's
counsel, they shall be frustrated, that He may do His
will and fulfill all His good pleasure.
