"Does Proverbs promise to much?" is a problem that Dr. Bruce Waltke addresses with some helpful thoughts. I have included three links to access the lecture in written and audio formats. My suggestion would be to pull up the text and use it to follow the audio.
Evangelicals confess the Book of Proverbs' inspiration and intellectually assent to its authority, but emotionally many cannot takethe book seriously because its promises seem removed from the harsh reality of their experience.
- Does Proverbs Promise Too Much? is an essay Dr. Bruce Waltke in the Andrews University Seminary Studies, Autumn 1996, Vol. 34, No.2, 319-336.
- The audio is also available on a podcast through Beason podcast

The palpable
rewards to which the gracious Lord obliges himself in the even
verses of 3:1-10 confront us with the theological problem, "Do they
promise too much? When applied to ordinary members of the
covenant
community, the interpreter of the text and of life may try to resolve the
tension by explaining that the problem lies in the human partner's
failure to keep the commands, not in the Lord s failure to keep his
obligations. The expositor, with Job's friend Eliphaz,
might conclude that
individuals do not experience these promises because of original sin:
"Can a mortal be righteous before God? Can a man be pure before his
Maker" (cf. Job 4:16-21).
As does Job, however, most expositors,
though conceding the problem of original sin, insist that thisis not
the reason for the apparently failed promises.
Their rejection of the facile explanation
by the likes of Eliphaz isvalidated by
the life of Jesus Christ. Though without sin, he apparentlydid not
enjoy these promises. Instead of enjoying long life, he died inthe
prime of life. Instead of enjoying favor with God and man, on thecross he
lamented, "my God, my God, why did you forsake me" (Matt. 27:46), as
the crowds jeered, "He trusts in God to deliver him; let Godrescue
him!" (Matt 27:43). Instead of a smooth path he experienced rejection at
birth, escaped the slaughter of the innocent, lived as an exilein Egypt,
confronted hostility every day of his ministry, and ended up a
lonely figure on the cross (cf. Isa 50:4-6). Instead
of psychological and physical
health, in the Garden
of Gethsemane he
experienced such trauma that
his sweat was like drops of blood falling to the ground (Luke
22:44). On the cross his malefactors so abused him that he no
longer
appeared human (cf. Isa 52:14). How can it be said
that thedevout have
barns overflowing with grain and vats that burst with new wine,
when the Epitome of Wisdom cautioned, "Foxes have holes and
birds of
the air have nests, but the Son of Man has no place to lay his head"
(Matt 8:20)?
To resolve this obvious tension created
by failed covenant promises, I will
reject three false solutions and propose four others to help us toward a
resolution of the problem.

Let us now turn to four solutions that I
find helpful. First, most would

Conclusion
If the life of Christ came to an end on
the cross, the covenant promises of
Proverbs, such as those found in the strophes of 3:1-10, failed.
However, if we pursue the career of Christ ...
