Speaking the Truth

The sermon opens with the story of philosopher Xanthus and his servant about the tongue — the best and worst of all foods — to highlight the importance of words in human life. The pastor notes that speech is the most important means of communication between people, capable of bringing comfort or causing harm, and cites Johann von Goethe's observation that speaking even a few reasonable words in a day is a rare thing. The sermon is grounded with President Roosevelt's 1932 inaugural address as an example of how truthful words, though difficult to hear, can bring courage in times of crisis.

The main body of the sermon explains that Jesus does not absolutely forbid oaths, since both the Old and New Testaments show God and His servants using them. The real problem Jesus addresses is how the Pharisees had turned oath-taking into a system of loopholes — developing elaborate formulas to distinguish binding oaths from non-binding ones, rather than teaching people to simply tell the truth. Jesus asserts that whether one swears by heaven, earth, Jerusalem, or one's own head, God hears and knows the heart, because He is the Creator of all things.

The sermon then develops from Matthew 12:33-37, teaching that words are a mirror of the heart: what comes out of the mouth reflects what fills the heart, and on the day of judgment people will give account for every careless word they have spoken. Multiple Proverbs passages are cited to underscore the consequences of lying, flattery, and false witness, with special emphasis that God considers a lying tongue an abomination.

The practical application section focuses especially on the destructive habit of gossip within the church. The pastor advises that when someone begins to tell you about another person, you should ask to write it down and confirm whether they would allow you to repeat it — if not, decline to hear it. Jesus' teaching in Matthew 18:15-17 on handling offenses is highlighted as the golden principle: go directly and privately to the person first, then bring witnesses only if necessary.

The sermon closes with a call to practice Jesus' simple but profound command: 'Let your yes be yes and your no be no — anything beyond this comes from the evil one.' The pastor encourages the congregation not to rely on elaborate oaths or promises, but instead to build their credibility through consistent truthfulness in everyday speech. This integrity in words is presented as a visible expression of genuine faith in the life of every believer.
