Life and Death in the Power of the Tongue - Choosing Words to Speak
Pastor Tan Thai · Mar 26, 2025
This sermon presents the critical importance of speech in the believer's life, based on Proverbs 18:21 and Jesus' teaching in Matthew 12:36-37. Words reflect one's thoughts, attitudes, and character, wielding tremendous power to influence relationships, honor, and even the spiritual life of others. Scripture teaches five qualities of speech: truthfulness, kindness, wisdom, boldness, and restraint, grounded in two foundational principles: truth and love.
The sermon begins by affirming that no subject is more necessary and practical than the matter of speech. Words express the thoughts of the heart, serving as the most important means of communication between people to convey desires, thoughts, feelings, and love. The fundamental reason is that Jesus Christ taught in Matthew 12:36-37 that on the day of judgment, every person will be judged by their own words. If believers truly understand this teaching, their daily speech will certainly change.
Scripture teaches five qualities of speech grounded in two foundational principles: truth and love. First, speech must be truthful, honest, and free from deception or fraud. Jesus teaches that words spoken must have the same level of truthfulness as an oath, whether in public or private settings, and toward all people equally. Second, speech must be kind, compassionate, lovely, and gentle rather than sarcastic, cursing, or malicious. Words possess power like a piercing sword—causing wounds not only to the body but to the inner life, spiritual life, and community relationships. Third, speech must be wise, timely, and appropriate rather than thoughtless and hasty. Fourth, speech must be bold and courageous in love, not evasive, twisted, or equivocal. Fifth, speech requires restraint and moderation—speaking less rather than more.
The sermon uses multiple Scripture passages and concrete examples from biblical history. The story of Abigail and Nabal (1 Samuel 25) illustrates how gentle, wise speech can change someone's mood and prevent disaster. The story of Prophet Nathan and King David (2 Samuel 12) demonstrates how using a parable is a wise method for helping someone recognize their own sin. The story of Michal mocking King David (2 Samuel 6:20) proves that sarcastic words have lasting consequences.
The sermon applies the message to the real life of the congregation. Believers must realize that words cause wounds not only visible like sword wounds but also spread widely through gossip and rumor, and once spoken, words cannot be retrieved. We bear responsibility to reflect before speaking, especially in family, church, and workplace. When others speak difficult truths, we must ponder them rather than react quickly. Ultimately, believers must understand that speaking truth requires courage, but truth accomplishes nothing if not spoken in love, with sincerity and genuine care.
