Jeremiah 17:9 – The Deceitful Heart

Gary W. Ritter

(Jeremiah 17-19; 1 Timothy 6)

There is a way of blessing and a way of cursing.  What we do in life will reflect this reality.  Do we wake up to the fact that God has put eternity into our hearts, and that we are to search Him out to find it?  Or do we reject the evidence God richly provides and disdain His good gifts so as to follow our own path?  Although the Lord has made Himself readily available to all, the uncomfortable fact is that most people in this world refuse to receive Him.  It’s just as Jesus said in Matthew 7:13 (NIV) that we should:

“Enter through the narrow gate. For wide is the gate and broad is the road that leads to destruction, and many enter through it.”

What is it about this wide gate and broad road that are so appealing?  How do we find that narrow gate?

At the core of these questions is what Jeremiah 17:9-10 declares:

The heart is deceitful above all things,

    and desperately sick;

    who can understand it?

“I the Lord search the heart

    and test the mind,

to give every man according to his ways,

    according to the fruit of his deeds.”

It all goes back to the issue of sin.  The iniquity that is resident in the DNA of each one of us makes the heart a liar to its owner.  The worldly advice of, “Follow your heart,” is probably not very sound.  It will deceive you into thinking something bad is good.  By itself, the heart doesn’t have a moral standard.  Feelings that come from the heart can be dishonest and illusory.  Why is the heart deemed sick?  Because its ills are wicked and incurable.  No one can even perceive the depths of the evil within it.

That is, no one but God.  He alone is able to see into every heart and to determine the character of every man.  Because He knows the end from the beginning, He can bless those whom He knows will follow Him and curse those who refuse that privilege.  In fact, Jeremiah 17:5 tells us:

Thus says the Lord:

“Cursed is the man who trusts in man

    and makes flesh his strength,

    whose heart turns away from the Lord.”

God is very clear.  When we choose not to seek Him and believe His promises; rather, we embrace the ways of the world, this is anathema to God.  It is abhorrent to Him; hateful, repugnant, an abomination; evil in every way.  Is it any wonder that a man who trusts in the ways of man rather than of God is accursed?

Ah, but what of someone who makes the conscious decision to revere, trust, and worship the God of the Bible through His Son, Jesus Christ?  What a difference!  See this contrast in Jeremiah 17:7-8:

“Blessed is the man who trusts in the Lord,

    whose trust is the Lord.

He is like a tree planted by water,

    that sends out its roots by the stream,

and does not fear when heat comes,

    for its leaves remain green,

and is not anxious in the year of drought,

    for it does not cease to bear fruit.”

Major points are repeated in Scripture, whether discussing blessings or curses.  Here, Jeremiah is effectively echoing Psalm 1:1-4:

Blessed is the man

    who walks not in the counsel of the wicked,

nor stands in the way of sinners,

    nor sits in the seat of scoffers;

but his delight is in the law of the Lord,

    and on his law he meditates day and night.

He is like a tree

    planted by streams of water

that yields its fruit in its season,

    and its leaf does not wither.

In all that he does, he prospers.

The wicked are not so,

    but are like chaff that the wind drives away.

How do we attain this blessed situation in our lives?  From the Old Testament perspective Jeremiah 17:14 puts it succinctly.  All one must do is call out:

Heal me, O Lord, and I shall be healed;

    save me, and I shall be saved,

    for you are my praise.

In New Testament language, the Apostle Paul tells us in Romans 10:9-10:

If you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. For with the heart one believes and is justified, and with the mouth one confesses and is saved.

There’s the heart again.  If we truly give our heart to the Lord, He will make it right.  No longer will we walk in deceit when we’ve surrendered our heart to God.  When He is our Savior and Lord, we are blessed.  What a rich and glorious inheritance that is!

As I’ve mentioned in the Author Note of previous articles, the Lord put it on my heart this year to write a daily essay relating to my practice of Reading Through the Bible in a Year.  Last year, that resulted in my producing the Awaken Bible Study Notes, a 4-volume set correlating with each quarter’s readings.  This year in my writings, truly through the grace of God, I’m producing the 4-volume Awaken Bible Commentary and Reflections series.  Volume 1, which covers January – March (Genesis 1 – Judges 5; Matthew 1 – Luke 7), is now available on Amazon in both paper and Kindle e-book formats at this link:

Awaken Bible Commentary and Reflections series Volume 1

If these daily writings have been a blessing to you, I hope that you’ll acquire this first book and the subsequent ones as I finish editing them.  My intent in all I write is to bring God the glory and to make His people think.  As in the Study Notes from last year, the Commentary and Reflections delve into the prophetic and supernatural nature of God’s Word, a combination you simply won’t find elsewhere.  They attempt to show the parallels to our times and the peril from the past when God’s people turn away from Him and His commands.  Scripture is very much a blueprint for today.

    “Why is the heart deemed sick? Because its ills are wicked and incurable. No one can even perceive the depths of the evil within it.” It is becoming more obvious with every passing day how true this is.

    Have you seen the story about the baby Baphomet the Church of Satan is placing inside the illinois State Rotunda?! Every God-fearing person recoils at the thought, let alone at the site, of this abomination. God is immeasurably patient, loving and long-suffering. But when He soon unleashes His wrath, many people (but sadly still not the majority) will cry out for His mercy and grace.

    I woke up this morning and what immediately came to my mind was the verse of Romans 8:28: “And we know that for those who love God all things work together for good, for those who are called according to his purpose.” I LOVE the Bible, every truth for life is inside it’s pages…what a loving God to tell us His values, His plans for us, His works and to give us a guide for living and for all of the things to come.

    We, who love Jesus and are saved, are safe in His salvation no matter what may come to us on earth.

    Ahhhh — It is very reassuring to have someone post that the REDEEMED heart is no longer deceitful & desperately wicked — instead, a believer’s new heart is righteous, holy, and indwell by God’s Spirit. Too many modern church organizations tell believers that their hearts are still ‘utterly depraved’, ‘deceitful’, ‘desperately wicked’… NO. That is the heart of a lost person, not the heart of one who is a new-born child of God. We believers still struggle against our flesh, but we’ve been ‘killed’ with Christ and resurrected IN him into new and eternal life. Selah. And Hallelujah!
