Is the Christian heart still wicked and deceitful? Or does God give us a completely new heart at the new birth? Is the Christian’s heart deceitfully wicked? You’ve heard that “deceitfully wicked” phrase from the Old Testament, but is such an indictment applicable to the regenerated Christian heart? The question is from a podcast listener named Micah. “Pastor John, hello! I was recently in a debate with a friend over Jeremiah 17:9: 9 The heart is deceitful above all things, and it is exceedingly corrupt: who can know it? ‘The heart is deceitful above all things, and desperately sick; who can understand it?’ I applied it to the ongoing sin-blindness in the heart of the Christian. My friend said I was taking a passage about unbelieving hearts and misapplying it to the Christian heart. However, in returning to the bigger context of Jeremiah 17:5 5 Thus saith Jehovah: Cursed is the man that trusteth in man, and maketh flesh his arm, and whose heart departeth from Jehovah. –13, I find myself even more convinced verse 9 is equally applicable to believers, especially in light of verses 7 and 8. What do you think? Is Jeremiah 17:9 9 The heart is deceitful above all things, and it is exceedingly corrupt: who can know it? about believers, unbelievers, or both?” Pastor John, how do you process this text and its context?
