This sermon examines Jeremiah 17:9-10 to reveal the profound corruption and deceitfulness of the human heart, which naturally flatters itself into thinking it is righteous. The preacher argues that self-deception arises from comparing oneself to others rather than God's perfect standard, leading individuals to ignore their inherent sinfulness. Despite this deep spiritual sickness, God intimately searches every thought and intention, leaving no secret hidden from His judgment. The message emphasizes that human efforts cannot cleanse this corruption, necessitating a reliance on Jesus Christ for forgiveness. Ultimately, the sermon calls listeners to acknowledge their sinful condition and turn to Christ for salvation before it is too late. View this on YouTube: https://www.youtube.com/watch?v=YJOyHzrtvQQ
