Deep Dive into From Plate to Person: Jesus’ Doctrine of Defilement and the Heart (Matthew 15:15–20)In Matthew 15:15-20, Jesus fundamentally redefines the concept of spiritual defilement by dismantling the Pharisees' reliance on external religious traditions. When religious leaders accuse His disciples of eating with unwashed hands, Jesus reveals that they elevate man-made rules over God's commandments, masking deep spiritual rebellion with outward piety. He explains that physical food follows a basic biological pathway, entering the stomach and leaving the body, and is therefore morally neutral and spiritually irrelevant. True contamination does not come from external substances, ceremonial lapses, or environmental factors.Instead, Jesus locates the absolute origin of moral pollution within the human heart. He provides a staggering catalog of sins, including evil thoughts, murders, adulteries, thefts, false witness, and slanders, demonstrating that the unregenerate heart is inherently corrupt and acts as a factory of idols. This theological truth emphasizes the doctrine of total depravity, refuting the modern secular illusion that humans are inherently good or merely victims of broken societal structures. Sin is an internal emission that breaks God's law and renders a person guilty before Him.Consequently, externalistic religion, moralism, and behavioral modification are entirely inadequate for addressing the true human condition. Since the core of human nature is polluted, people cannot achieve holiness through ceremonial compliance, self-improvement, or manageable routines. The only remedy for this profound internal corruption is sovereign grace. Sinners require the regenerating work of the Holy Spirit to receive a new heart, and they must rely entirely on the atoning blood of Christ, who alone possessed perfect internal purity, to cleanse their conscience and secure true justification.Reformed Theologian GPT: https://chat.openai.com/g/g-XXwzX1gnv-reformed-theologianYoutube: https://www.youtube.com/@ReformedExplainerSpotify Music: https://open.spotify.com/artist/1t5dz4vEgvHqUknYQfwpRI?si=e-tDRFR2Qf6By1sAcMdkdwhttps://buymeacoffee.com/edi2730

Women with Dyslexia Podcast: Living the Gospel with Power Hope B This podcast is designed for women with dyslexia who believe that God can do something new. The Apostle Paul says that we are transformed by renewing our minds to do what pleases the LORD, which is His will. When our minds are renewed (neuroscientists call this neuroplasticity), we are transformed. This podcast will contain short biblical messages designed to replace our old negative thinking with the truth found in God’s word. It is devoted to encouraging and inspiring adult women with dyslexia by listening to biblical truths that will uplift and challenge them to find a place for dyslexia in their lives and let Christ take center stage of their lives. To benefit from these short yet powerful messages, I recommend making these podcasts part of your morning and evening time with the Lord. Thank you for joining me.
