“The heart is deceitful above all things and beyond cure. Who can understand it? I the LORD search the heart and examine the mind,to reward a man according to his conduct, according to what his deeds deserve.” (Jer 17:9-10).
When we hear that we are broken, that something is terribly wrong with us, it is not the comforting news we wish to hear. We want to be told we are good, kind and loving. Why would we want to hear we are deceitful, greedy, immoral, selfish and evil (Mt 7:11, Gal 5:19-21)? Facing oneself is not easy. The reflection we see in the mirror can be confronting. God does not pull any punches in describing humanity’s condition. In Romans 3:23 we read ALL Have fallen short of the glory of God. God’s universal judgement of the entire human race. The diagnosis, however, does not improve as the Bible’s message unfolds.
The preceding verses to Jeremiah 17:9 announce an ominous warning – “This is what the LORD says: “Cursed is the one who trusts in man,who depends on flesh for his strength and whose heart turns away from the LORD. ” (Jer 17:5). Trusting in our own strength or trusting in other’s strength is a form of idolatry. In other words, trusting in the creation rather than the Creator. Verse 17:9 tells us why this is such an issue. The problem lies within the human heart itself.
Feinberg (1986) states “The source of all human difficulty is the human heart (Prov 4:23). In OT usage the heart signifies the total inner being and includes reason. From the heart come action and will.” Our hearts, our inner being, are far from perfect. Once in a sermon I singled out a man in Church and asked him if I were to place all of his thoughts for the year on a projector screen, that the whole congregation could see, would he be comfortable? He adamantly shook his head. In the Sermon on the Mount Christ lets us know that even our thoughts are vitally important to God – and indeed will be judged. Anger the same as murder, a lustful look the same as adultery (Mt 5). Christ was getting to the core of the matter – the deceitful heart we all carry.
This verse tells us God searches our hearts and looks at our deeds (Eph 2:10, Jm 2:26, 1 Jn 3:18, Rev 2:2, 2:19, 3:1, 3:8, 3:15). Our deeds carried out in the body will clearly be judged (Rom 2:6-7). To those that persist in doing good there will be reward and to those that persist in doing evil – punishment. How then can we change from having this deceitful and corrupt heart to having one that seeks to do good unto others? Put simply – we can’t, by ourselves it is beyond cure. Only God can do it.
He tells us the cure Himself in Ezekiel 36:26 – “I will give you a new heart and put a new spirit in you; I will remove from you your heart of stone and give you a heart of flesh”. That new heart is received when we repent and turn to our Saviour Jesus Christ and make Him our Lord . Through His Spirit the heart is circumcised. It softens, its hardened exterior cracks (usually in tears) and we in-turn change. Sanctification begins, our healing and metamorphosis initiates. It is then we can literally see the fruit of our good deeds (Eph 2:10). If they are not present, as James explains – are we really saved at all? If the continuous act of charity (love in action) is not present, what is going wrong? Or are we simply whitewashed walls, still corrupt on the inside and resisting the Holy Spirit in self righteous pride (Acts 7:51). Billy Graham’s message of the new heart is worthy of note when regarding heart change. Watch it here.
