"The heart is deceitful above all things, and desperately sick; who can understand it?" (Jeremiah 17:9, ESV)
In the mid 50's there was a radio and television program called "The Shadow." It was a crime/mystery program and the Shadow solved crimes. The show opened with this exclamation "Who knows what evil lurks in the hearts of men?" This was followed with a wicked laugh and the proclamation that "the Shadow knows."
Well I hate to bust the Shadow's bubble but no, the Shadow does not know the hearts of men for the Bible tells us that the heart is so utterly wicked that no man can know the heart. In fact, scripture tells us the heart is utterly depraved and capable of all kinds of evil without limits or constraints on it.
I have often heard it described as a well into which you throw a rock and wait for it to hit the bottom but it never does because there is no bottom to the heart of stone.
Jeremiah tells us that the heart is deceitful above all things and not just wicked but desperately wicked. Jeremiah is writing to Israel about the coming judgement for their rebellion against the Lord God. He tells us that the heart does not need a renewal or a fresh make over but man needs a completely new heart, one not made of stone but made of flesh. Not a new covering with fig leafs but a new creation.
Reader, how about your heart? Has your old heart of stone been removed and a new heart of flesh received, or has your old heart of stone simply been white washed and covered with new fig leafs to hide your sin? The scriptures tell us, "Therefore if any man be in Christ, he is a new creation; old things are passed away; behold; all things are become new." (2 Cor. 5:17, KJV)
Flee to Christ; and plead for mercy and forgiveness of sin and find there life everlasting, forgiveness of sin, and a new heart made of flesh that loves and serves Christ.
