Guard Your Heart
Pastor Tan Thai · Feb 15, 2015
This sermon uses Valentine's Day as a starting point to address the more important spiritual meaning of the heart, based on Proverbs 4:23. The pastor presents the sinful condition of the human heart, God's promise of a new heart, and a call to receive Jesus Christ for regeneration.
The sermon opens by introducing Valentine's Day with striking spending statistics in the United States — nearly 19 billion dollars annually — alongside the historical origin of the holiday tied to Saint Valentine during the reign of Emperor Claudius II. The pastor then transitions to analyzing the meaning of the heart in literature, medicine, and especially in Scripture, citing Proverbs 4:23: "Guard your heart above all else, for it determines the course of your life."
The sermon highlights two key biblical truths about the heart. First, God has placed "eternity" in every human heart (Ecclesiastes 3:11), causing people to long for something beyond the satisfactions of this life. Second, Scripture describes the sinful heart with several serious spiritual diseases: a deceitful heart, a sorrowful heart, a proud heart, a hateful heart, and a hardened heart — each illustrated with passages from Proverbs, Jeremiah, and Ephesians.
The pastor uses the story of Isaac and Rebekah in Genesis 24 to illustrate a heart that is empty and waiting to be filled by love, then draws a parallel to the spiritual heart of every person that needs to be renewed by God. God's promise in Ezekiel 36:26 — "I will give you a new heart" — is emphasized as the foundation of hope.
The application section calls listeners to honestly confront their own sinfulness, reject the notion that human nature is inherently good, and instead repent and receive Jesus Christ. The pastor quotes Romans 10:8-10 to show that salvation comes through faith in the heart and confession with the mouth, with the promise that the Holy Spirit will come to transform and guard the new heart that God gives.
